Merge origin/master into garrytan/managua-v3

Resolves v0.34.0.0 (W1-W8 code intelligence) with master's v0.33.2.1 +
search-lite work (query cache + intent weighting + token budget + drift
watch + metric glossary + search modes).

Conflict resolutions:
- VERSION / package.json: kept 0.34.0.0 (mine; higher than master's 0.33.2.1)
- CHANGELOG.md: both entries preserved; reordered so v0.33.2.1 sits above
  v0.33.2.0 (semver order)
- src/cli.ts CLI_ONLY: union of both — `edges-backfill` (mine) + `cache`
  (master)
- src/core/migrate.ts: renumbered my migrations to avoid collision with
  master's query_cache_search_lite (v55), query_cache_knobs_hash (v56),
  search_telemetry_rollup (v57). My `edges_backfilled_at_v0_33_2` moves
  v55 → v58; my `code_traversal_cache_v0_34` moves v56 → v59. Code refs
  in `src/core/code-intel/traversal-cache.ts` and the paired test
  updated to match.
- src/core/operations.ts query op: kept master's `hybridSearchCached`
  routing (search-lite cache integration) AND my `sourceId` resolution
  block (D4 source-routing fix from v0.34 STEP 0). Both apply.

Verification:
- `bun run typecheck` clean
- `bun run verify` clean (includes check-cli-executable, check-jsonb,
  check-system-of-record, check-eval-glossary-fresh, etc.)
- Migration v50→v59 apply cleanly on PGLite in isolated test runs
- Individual test files pass (e.g. test/search-lang-symbol-kind.test.ts:
  9 pass / 0 fail in 913ms)

Known follow-up: the parallel test shard runner times out some
beforeAll hooks at the default 7s budget. Tests pass when run
sequentially (`--max-concurrency=1`); 27/0 confirmed across 3 sample
files in 2.4s sequential vs timeouts under parallel-shard contention.
Master added 4 new migrations (v55-v57 + search-lite related)
increasing per-test-file PGLite init cost; on 8 shards racing for OS
resources, some shards hit the 7s ceiling. This is a test-infrastructure
issue (shard isolation under heavier migrations), not a code-correctness
issue. Fix is a follow-up: either raise shard test timeout, reduce
shard count, or migrate to fixture-based engine setup for hot tests.
