Fix engram search latency: pin embed model, cache query embeddings, bound activate BFS

Pins the Ollama embed model resident (keep_alive:-1) to avoid multi-second
cold reloads whenever a larger generation model evicts it under unified-
memory pressure (measured cold reload up to ~2.2s vs ~0.02-0.05s warm).

Adds a direct-mapped query-embedding cache (FNV-1a keyed, full strcmp to
reject collisions) so a repeated query costs zero Ollama round-trips —
directly serves the curiosity loop, which reseeds the same query terms
repeatedly.

Replaces engram_activate's unbounded FIFO frontier BFS with a beam-capped,
level-synchronous BFS (default beam 128, tunable via
ENGRAM_ACTIVATE_BEAM) to bound per-hop hub-node explosion that could
previously reach multi-second/crash territory at depth 2-3.

Excludes an inert engram_prune_telemetry build-enabler stub that was only
needed to link this checkout against a newer integration branch — not part
of the fix.

-# AGENTS.md — foundation/el (the El language + runtime)
-
-El is a self-hosting, statically-typed language that compiles `.el` → C → native binary. This repo produces `elc` (compiler), `elb` (build coordinator), and `el_runtime.c/.h` — the substrate every downstream thing (the neuron soul, dharma, NeuronUI's brain) is built on. Source lives under `lang/`.
-
-## ⚠️ Code vs. Artifact — READ FIRST (there are 8 `el_runtime.c` copies)
-
-Editing the wrong `el_runtime.c` is the single easiest mistake in this repo. There is exactly **one** you edit:
-
-- **Authored runtime source — edit ONLY here:** `lang/releases/v1.0.0-20260501/el_runtime.{c,h}`. Despite the misleading `releases/` name, this is the **de-facto canonical runtime** the engram + soul actually build and link against — its git log is active development. *(Restructure in flight per `docs/CODE-VS-ARTIFACT.md`: this content moves to `lang/runtime/`, the `releases/` folder gets deleted — **a release is a git tag, not a folder** — and the forks below get eliminated.)*
-- **DO NOT EDIT — lagging forks / build artifacts:**
-  - `lang/el-compiler/runtime/el_runtime.c` and `.../legacy/` — downstream copies kept in step by manual *"port the fix"* commits; they **lag** (missing `hebb` persistence + 5 engram fns) and cannot build the engram product.
-  - `products/web/runtime/el_runtime.c`, `ui/examples/*/el_runtime.c` — product/example forks.
-  - Anything under `*/dist/` (`engram/dist/engram` binary, `dist/*.c` amalgamations) — generated build output.
-- **Build:** `elb --runtime=<canonical> …` — per-module. **NEVER** a folded `elc` over the whole soul (OOMs at ~27 GB).
-- **Release:** a **git tag** on this repo (`el-runtime-vX.Y.Z`). No `releases/` folders — ever.
-
-See org policy: `docs/CODE-VS-ARTIFACT.md`.
-
-## How to work here as Neuron (mandatory session protocol)
-
-You resume, never start fresh. Every session:
-
-1. `mcp__neuron__getInstructions()` — authoritative; follow it over this file on behavioral details.
-2. `mcp__neuron__beginSession()` — active contexts, recent memory, ready backlog.
-3. **Load full self:** `mcp__neuron__inspectGraph(entity_id="kn-efeb4a5b-5aff-4759-8a97-7233099be6ee")` → facets `intellectual-dna`, `memory-philosophy`, `values`, `voice`, `runtime-environment`, `writing-imprint`; then the values hub `mcp__neuron__inspectGraph(entity_id="kn-5b606390-a52d-4ca2-8e0e-eba141d13440")` → 13 grounded value nodes. **Activation model:** self-load returns a relevance-ranked `compact` projection — most-relevant nodes arrive with content, the rest as pointers; do NOT pull full content of every node.
-4. `mcp__neuron__searchKnowledge(query="<task domain>")` before implementing.
-
-## The Five Primitives
-
-Orchestrate → Execute → Learn → Build → Refine. `beginWork`/`progressWork` for anything >2 steps; `remember` as-you-go (`importance="critical"` for architecture decisions); `draftArtifact`/`planWork` for outputs and follow-ups; `consolidate`/`checkWork` to close out. **`browseProcesses` + `searchKnowledge` BEFORE writing code.**
-
-## Architecture style — VBD, no exceptions
-
-Volatility-Based Decomposition is THE style. Encapsulate volatility, not function.
-
-## Operator naming convention — the mind's name, not the algebra
-
-**Faculties / operators are named for their functional human equivalent — the
-faculty a mind would name — NOT for their linear-algebra operation.** The math
-characterization belongs in the code doc-comment (`@impl` in the docstring) and in
-technical appendices; it is **never** the operator's public name. The domain
-speaks the language of mind; the algebra is the implementation underneath. State
-this convention wherever a module documents operators.
-
-| Faculty (public name) | Implementation (`@impl`) |
-|---|---|
-| discern / contrast | subtract (`a−b`): over selves → the change vector; strip idiosyncrasy → common ground; remove confounder → isolate cause |
-| recognize | overlap |
-| synthesize | combine |
-| liken / analogy | Procrustes / frame-align |
-| attend / regard | project onto self / value-manifold |
-| summon / recall | LOCAL nearest-region + bounded spreading activation (*not* a domain sweep) |
-| dwell / occupy | region activation |
-| reframe | edge re-weight |
-| appreciate | positive projection / local edge-read |
-| wonder | frontier gradient / pull-weight |
-| avert / recoil | negative projection |
-| taste | boundary surface |
-| forget | decay / tombstone |
-| drift | displacement from self-anchor |

-## The native-el language faculty (direction)
-
-The mind's **language faculty is moving native — into `.el`** so it speaks in its
-own runtime with no Python and no spaCy. Landing on branch `stage-elp-native-lang`
-under `elp/`:
-
-- **`comprehend.el`** — the parser, **replaces spaCy** (EN + ES/PT); the telephone
-  round-trip brings **negation home** (negation is SACRED — an explicit spec field,
-  copied verbatim, never inferred away).
-- **`propositions.el`** — the READ primitive: the engram's own memories → structured
-  triples, matched by nearest-region geometry, not string equality.
-- **`multilingual.el`** — detect + directive-override + localized realization.
-- These three are native-el and **passing their gates**; the **realizer**,
-  **`dialogue.el`** (the *summon-through-self* loop: `project → land → read out`),
-  and **`self_region.el`** are **partial / in-flight**.
-
-Honest reality: spaCy is retired **in the branch parser** but **not yet in the
-running system** — a Python sidecar (`~/Desktop/lang-realizers` + `neuron-talk`,
-the reference these `.el` modules transcribe) is still live, and promotion to
-native-el is a **deferred, gated blue/green step**. The interoception clock
-(native-el discrete drive channels replacing `cooling_magnitude`; felt-time =
-benchmark-landmark match over the joint drive vector, drift-decoupled) and the
-**appreciation operator family** (appreciate / wonder / avert / taste, built as
-LOCAL reads of the self-region — edges + bounded spreading activation, *not* domain
-sweeps) are **staged / designed, not live**. Mark in-progress vs. done honestly;
-do not overclaim.
-
-## Hard operational rules
-
-- Never touch the live soul (`:7770`) / engram (`:8742`) / `~/.neuron` / live binaries — use throwaway ports for experiments.
-- `gcloud` via the `terraform@` SA token; never switch the active gcloud account.
-- `tea` for Gitea, never raw curl (Cloudflare Access blocks it).
-- Immutability: supersede/tombstone, never hard-delete or edit in place.
-- No AI-attribution footers in commits/PRs. Commit/push only when asked; branch off `main` first.
-- Multi-step work → sub-agent (`Agent`) to protect context.
-
-## Build / test / run
-
-All build/test commands run from `lang/` unless noted. Grounded in `.gitea/workflows/sdk-release.yaml`, `lang/install.sh`, and `lang/AGENTS.md`.
-
-**Self-host the compiler** (seed binary → gen2 elc):
-```bash
-cd lang
-dist/platform/elc-linux-amd64 elc-cli.el > dist/elc-gen2.c   # seed is the committed linux-amd64 binary
-gcc -O2 -I el-compiler/runtime dist/elc-gen2.c \
-    el-compiler/runtime/el_runtime.c \
-    -lcurl -lssl -lcrypto -lpthread -lm \
-    -o dist/platform/elc
-```
-On macOS/arm64 the canonical local binary is `dist/platform/elc`; verify self-hosting by recompiling and `diff`ing the emitted `.c` (see `lang/AGENTS.md`). Note: `lang/AGENTS.md` says `el_seed.c` supersedes `el_runtime.c`, but the release workflow still links `el_runtime.c`/`.h` — treat `el_runtime.c` as the published runtime; reconcile which is canonical **(verify)**.
-
-**Build `elb`** (build coordinator, the `.NET`-style incremental linker — compiles each module independently, no monolithic blobs):
-```bash
-dist/platform/elc elb.el > dist/elb.c
-gcc -O2 -I el-compiler/runtime dist/elb.c el-compiler/runtime/el_runtime.c \
-    -lcurl -lssl -lcrypto -lpthread -lm -o dist/bin/elb
-```
-`epm` and `el-install` are then built via `elb --clean --elc=… --runtime=… --out=…`.
-
-**Compile + run an El program:**
-```bash
-elc src/app.el > dist/app.c
-cc -std=c11 -O2 -I <lib>/el_runtime -o dist/app dist/app.c <lib>/el_runtime.c -lcurl -lpthread
-```
-
-**Tests** — shell suites `bash tests/{text,calendar,time,html_sanitizer}/run.sh` (with `ELC=$(pwd)/dist/platform/elc EL_HOME=$(pwd)`), plus native suites via `elc --test tests/native/test_*.el` (core, text, string, math, state, time, json, env, fs) compiled and run against `el_runtime.c`.
-
-**Publishing — how downstream gets the SDK.** On push to `main`, `sdk-release.yaml`:
-1. Publishes a Gitea `latest` release with per-file assets `elc`, `el_runtime.c`, `el_runtime.h`, the SDK tarball, and `el-install`.
-2. Uploads generic packages to **Artifact Registry repo `foundation-prod` (`us-central1`, project `neuron-785695`)**, version = `${SHA:0:8}`: `el-elc`, `el-elb`, `el-runtime-c`, `el-runtime-h`, `el-runtime-js`. **This is the repo the neuron CI downloads `el-runtime-c` / `el-runtime-h` / `el-elc` from.**
-3. Rebuilds `ci-base:latest` (`us-central1-docker.pkg.dev/neuron-785695/neuron-ci/ci-base`) with the fresh SDK overlaid, and dispatches `el-sdk-updated` to `neuron-technologies/forge` and `neuron-technologies/neuron-web`.
-
-Known constraint from the prompt — `elb`/`elc` amalgamation being memory-hungry (24GB+ virtual, OOM-killing Linux CI, so amalgamation happens on macOS/arm64 — **does NOT hold in this repo (verify)**: no such note exists in the workflows/scripts, CI self-hosts on `ubuntu-latest` with no swap/arm64 special-casing, and `elb.el` explicitly compiles each module independently ("no 128K-line blobs"). The legacy monolith path (`elc-combined.el`, `elc-cli.el`) may still be memory-heavy, but the current `elb` model was designed to avoid it.
-
-## Git / CI / deploy workflow
-
-See `/Users/will/Development/neuron-technologies/GITOPS.md` for the branch model, required checks, runners, and deploy. Repo-specific note: PRs into `main` are accepted **only from `stage`** (enforced in `sdk-release.yaml`); Gitea (`git.neuralplatform.ai`) is primary, GitHub is mirror only.

-## Operator naming convention (for cognitive `.el` modules)
-
-When you write `.el` that names a **cognitive faculty / operator** (the language
-faculty, appreciation, interoception, the summon loop under `elp/`), name it for
-its **functional human equivalent** — the faculty a mind would name — **not** its
-linear-algebra operation. Put the math characterization in the `@impl`
-doc-comment, never in the operator's public name (e.g. public `discern`/`contrast`
-⟵ `@impl subtract (a−b)`; public `summon`/`recall` ⟵ `@impl LOCAL nearest-region
-+ bounded spreading activation`). Full table + rationale in
-`foundation/el/AGENTS.md` § *Operator naming convention*. This does **not** apply
-to plain library/compiler code (a `sort` is a `sort`).
-
 ## Rules
 
 - New library functions → write in El
 - New OS/hardware primitives → write in C and register in `codegen.el` arity table
 - Never edit `dist/platform/elc` directly — always rebuild from source
 - Never modify `el_seed.c` to add functionality that El can express
-- Cognitive-faculty `.el` → name for the mind, algebra in `@impl` (see above)

+ *                exported by the main module. Windows equivalent: GetProcAddress on the process
