bigmerge 40bb6ff579 swarm: orchestrator, CCR context compilation, containment rules, primitive seam
- swarm.el: coordinator running fan-out/converge on El NATIVE threads
  (thread.el spawn/join) in bounded concurrency waves, order-preserving;
  convergence strategies collect/merge/vote/reduce; integer per-mille failure
  threshold (El float division is unreliable — avoided deliberately).
- ccr.el: per-worker Compiled Context Routing — retrieval/scoping/compaction
  into a bounded, minimal package; the compiled-context boundary is the
  security boundary (a worker cannot receive or leak sibling inputs).
- containment.el: the three Swarm containment rules enforced via scope tokens
  (Rule 1 no join, Rule 2 no open, Rule 3 no lateral edge) + execution-tree
  lateral-edge check.
- primitives.el: attend/think/intend/act/learn seam the swarm composes over,
  with engram-backed fallbacks and an explicit binding point for the reshape.
- prototype json_array_push in el_runtime.h (defined but unprototyped).

test_swarm: 12/12 — native fan-out/converge, bounded concurrency, durable
tracking, CCR bounding + non-leak, and all three containment rules.

// swarm.el the swarm orchestrator: bounded parallel agent execution.
//
// Implements Swarm Architecture's single pattern fan out, execute independently,
// converge on El's NATIVE concurrency (thread.el spawn/join). No external
// orchestrator: a swarm is a coordinator (this file, the main thread) that mints
// a correlation identity, compiles a bounded CCR context per worker, dispatches
// workers as native pthreads, tracks every unit of work, and converges the
// results before returning control to the parent step.
//
// The five properties of every swarm (Swarm §2.1) are all present:
// parent step -> swarm_run is called from one process step
// task blueprint -> `blueprint` name + knowledge refs, run by every worker
// input set -> `inputs_json`, one item per worker
// convergence -> `strategy` in config (collect|merge|vote|reduce)
// correlation ID -> minted here, threaded through tracking + every worker
//
// Containment (Swarm §3) is enforced: the caller must hold a coordinator/absent
// token to open a swarm (Rule 2), each worker is stamped a closed worker token
// (Rules 1+3), and workers share no mutable state (the coordinator is the only
// journal writer).
// worker entry the top-level (String)->String fn native threads run
//
// Every El fn compiles to a global C symbol; spawn() resolves this by name via
// dlsym and runs it in a pthread. The envelope carries everything the worker is
// permitted to see its compiled context and nothing else (§9.3).
//
// Returns a result JSON: {worker_id, status:"completed"|"failed", output|error}.
