Renn F 984083c7e8 fix(gateway): bound the briefing's RAG memory leg; skip cold conventions re-resolution in claim_review
Two remaining 120s-wall consumers found tracing live 504s on the
redeployed stack (claim_review completing at exactly 120s with a
~74s silent tail after the bounded evidence legs gave up):

_institutional_memory's similar_memory call rode the Ollama
embedder's 120s read timeout unbounded inside every full briefing
(give_me_work / i_will_work_on / i_will_plan / resume pass task=t),
so a saturated embedder could eat a claim verb's whole budget. It
now runs under asyncio.wait_for with the new
institutional_memory_timeout_seconds (default 8s) and degrades to a
first-class {status: "timeout", lessons: []} block — the briefing
is enrichment, never the thing that kills a verb.

claim_review's advisory conventions leg trusted that the diff /
files_changed legs had warmed the workspace; when those legs timed
out, conventions_check_for_task's unwrapped setup phase re-hit the
same cold/contended git ops (30s-bounded subprocesses in sequence,
clone repair up to 300s) and ground on until the verb wall. The
evidence build now skips the conventions leg whenever the git legs
already recorded gaps, emitting the existing could_not_run shape
plus an evidence_gaps note instead of a 504. Fail-closed
enforcement (i_am_done / pr_pass) is untouched.

Gate: 15481 passed, 459 skipped; ruff/mypy/xenon/vulture/bandit/
pip-audit/deptry/import-linter/foundation-check green.
