Bound beginSession/compileCtx payloads to a compact digest

Port the payload-bounding fix (PR #102, commit 872120c) onto main. The
session-init endpoints projected unbounded engram nodes (~900KB), closing
the MCP client socket on every beginSession. Cap the lists (8 activated /
10 recent for begin_session, 10/20 for compile_ctx) and project each node
to a light identity + a bounded, UTF-8-safe content snippet via
api_compact_node / api_compact_activated / api_utf8_trunc. Response drops
~900KB -> ~12KB; full content stays available via recall/fetch/inspectGraph.

Regenerate dist/soul.c (the CI-built amalgamation) and dist/neuron-api.c
from source. The soul.c regen also compiles in already-merged source the
previously-committed soul.c was stale against (agent write/edit receipt
fixes, #100/#101); verified via scripts/verify-soul-contract.sh
(PRESENCE + IMMUTABILITY PASS) and a clean CI-style cc build.
