docs: carry the correspondence corrections, because a stale doc builds the wrong thing

The docs described a mind made of subsystems — a grounding subsystem, a wonder
manifest, a dreamer on a beat, faculties as arguments to one call. Each of those
is a supervisor invented for something that should be a property of the
substrate, and two of the documents carrying them are load-bearing for a build
agent: cognitive-architecture.design.md says "a build agent executes from this
doc", and tools/api-reshape/README.md marks the refuted shapes PROVEN on a live
clone.

Corrections carried, per lang/spec/correspondence-and-censorship.md (PR #149)
and lang/spec/runtime-ownership.md:

- Grounding is not a subsystem — it IS the edge weight. grounded-by as a
  relation type should not exist; grounding is a property of a relation, not a
  relation between nodes. Never computed on demand.
- Faculties are operations, not parameters. reason changes the estimate, induce
  changes the parameters, abduce changes the structure — a write, which
  GeoGradient cannot express. A write is not a parameter of a read.
- Wonder is the boundary, not a manifest. Curiosity is wonder crystallized at a
  nucleation site: one thing at two phases. Removed wonder from the operator
  table in AGENTS.md.
- Consolidation is ambient, not scheduled. A brain has no cron job. The presence
  of a ticker is the diagnostic.
- co_registration is deprecated — it averaged a per-edge property into a region
  scalar, so opposing sites cancelled. GeoEdge.discord replaces it. Nothing new
  may read it.
- In an immutable substrate, any mechanism that refuses a write is either
  redundant with immutability or an epistemic constraint misfiled as a
  protective one.

The two design docs are marked superseded-in-part with the refutation at the
point each claim is made, not rewritten. Preserving what was argued down is the
point of an immutable record.

Also measured and corrected while verifying the above: engram/README.md
documented a Rust engram-core crate on sled with "flat cosine scan until scale
demands HNSW" — there is no Rust in engram/ and HNSW is the index; lang/releases/
no longer exists, so both README.md and AGENTS.md pointed at a deleted path for
the authored runtime; language.md listed the engram_* and http_* runtimes as
stubs. Added language.md §20 for geometry-as-a-value, realizers and transduce
(#144), which had landed with no spec coverage.

Documentation only. No .c, .h, or .el file is touched.

In an immutable substrate, any mechanism that refuses a write is either redundant with immutability, or an epistemic constraint misfiled as a protective one. The identity view's real job is the **crystallized relational neighbourhood**: self is not a stored document but the shape that falls out of everything connected to it, and the neighbourhood **is** the grounding. A measurement made the other way round — "86 neighbours, 0 `grounded-by` edges" read as evidence of ungroundedness — was malformed: those 86 edges *are* its grounding.)*
 6. **Temporal View** — `recall_at` / time-travel: how the geometry looked at a past moment, what changed since, drift over time. Pairs with temporal-self reconstruction.
 7. **Schema / Type View** — the "information schema" of the geometry: node types, edge types, layers, tiers, counts.
