chameleon 4.1.1

Fixes from the qa66 whole-plugin, from-scratch, real-invocation campaign
(512 cells across 8 language/framework rows plus support-process and
hostile-input rows; 10 findings, every one adversarially re-verified in a
fresh isolated workspace before being fixed, and every fix re-verified with
the finding's own real repro afterward).

Fixed

• A from-scratch bootstrap of a no-remote repo (fresh git init, no origin)
  no longer leaves permanently-orphaned plugin-data directories: after the
  orchestrator mints the repo_uuid, bootstrap_repo invalidates the
  same-process repo-id cache, recomputes the final identity, scopes the drift
  baseline to it, and sweeps the pre-uuid lock directory (skipped whole when
  a concurrent claimant holds the lock, so contention never splits the
  bootstrap mutual exclusion). detect_repo's
  legacy-id re-trust hint now uses a non-creating probe
  (trust_state_probe) instead of minting an empty directory per probed
  identity.
• The five committed-index loaders (symbol signatures, calls index, exports
  index, reverse index, function catalog) honor the COMMITTED transaction
  sentinel like every other profile loader: a torn .chameleon (crash
  mid-commit, unresolved merge) now reads as index-unavailable across
  search_codebase/get_callers/get_callees/query_symbol_importers/
  get_blast_radius/get_duplication_candidates instead of being served as
  ground truth while sibling tools report profile_corrupted for the same
  tree. Doctor reports that torn state directly ("profile is uncommitted ...
  run /chameleon-refresh") instead of misreading each refused loader as a
  stale-schema artifact.
• The documented "5 seconds once escalated" posttool-verify cooldown is
  reachable: the self-correction window no longer zeroes the dedup TTL. The
  byte-identical-content digest gate already guarantees a real fix is never
  swallowed, and because every violating verify re-stamped
  last_violation_at, the zeroing had made the dedup structurally
  unreachable for any file that ever violated.
• A partial refresh stamps the carried conventions.json with the refresh's
  generation, so the bundle stays generation-consistent; doctor's
  cross-artifact check now mirrors the loader's actual gate (four artifacts)
  and reports a lagging conventions.json as staleness instead of falsely
  claiming "the bundle is unloadable" after every partial refresh.
• FastAPI package-form roles: app/schemas/ and app/dependencies/ (and
  deps/, crud/) now role-bucket like their filename forms, so a
  dependencies file no longer inherits the Pydantic schemas archetype's
  "extends BaseModel" guidance via path fallback, and a schemas package
  names cleanly (schema) instead of an opaque cluster hash.
• .gitattributes-template routes the structured idiom store
  (.chameleon/idioms/**) to the merge driver: two branches that each
  taught a different idiom always collide on the .view_digest sidecar,
  and the unrouted merge wrote raw conflict markers into live store state.
  With the route, per-idiom JSON records merge and the sidecar is declined
  whole (accept either side; the next teach or refresh recomputes it).
