regen dist: rebuild soul.c from corrected sources (OOM gone, Track B compiled in)

Regenerates the combined dist/soul.c and per-module dist/*.c from the current
El sources, on top of the elc-source-typo fixes (PR #77) and the Track B
threat-to-others routing (PR #76), both already on this branch.

Validated end to end under a physical-RSS watchdog (macOS silently ignores
ulimit -v / RLIMIT_AS, so every elc/elb run was RSS-polled and kill -9'd at a
3GB ceiling, one module at a time):

- OOM is GONE. The stale dist/soul-with-nlg.el (which still carries the
  malformed string literals) explodes to 3.3GB+ and is watchdog-killed at ~90%.
  With the typos fixed, every one of the 48 modules compiles at <=18MB peak RSS,
  and the full flat amalgamation compiles as a single translation unit at ~68MB.
  The 700GB pathology was purely the unbounded-parser-on-malformed-literal loop;
  no malformed construct means no loop.
- The regenerated soul.c contains Track B: safety_classify_hard_bell ->
  threat_other -> safety_hard_directive routes credible threat-to-others to 911
  and explicitly NOT to 988 / the safety contact. Verified in source, in the
  emitted C, and in the linked binary's strings. Track A (abuse / self_harm)
  is unchanged and still checked first.
- The regenerated soul links to a working native arm64 binary and boots: serves
  on a throwaway port, /health returns 200, awareness loop runs.

Also fixes one source blocker discovered during regen (unrelated to the typos
or Track B): chat.el handle_chat_agentic left a void `if { println(...) }` in
value position, which the current elc lowers to `_if_result = (println(...))`
(assigning void) -> invalid C. Bound an explicit Bool so the branch is
non-void; behavior unchanged (still only logs on persist failure).

NOTE (runtime dependency, for controlled deploy): this branch's chat.el calls
engram_get_node_by_label, which the canonical el-compiler/runtime does not yet
declare/define (the release runtime v1.0.0-20260501 has it; the newest runtime
has arena + http_serve_async but not this). Building the soul requires a runtime
that has all three. Land engram_get_node_by_label into the runtime package
before this soul.c can be built in CI.

Do not merge — regen + Track B going live is a controlled-deploy call.
