playbook_lift: harness expansion + reality test #001 (7/8 lift, 87.5%)

The 5-loop substrate's load-bearing gate is verified — playbook +
matrix indexer give the results we're looking for. Per the report's
rubric, lift ≥ 50% of discoveries means matrix is doing real work;
7/8 = 87.5% blew through that.

Harness was structurally hiding bugs behind a 5-daemon stripped boot.
Expanding to the full 10-daemon prod stack surfaced 7 fixes in cascade:

1. driver→matrixd: {"query": ...} → {"query_text": ...} field name
2. harness temp toml missing [s3] → wrong default bucket → catalogd
   rehydrate 500 on first call
3. harness→queryd SQL probe: {"q": ...} → {"sql": ...} field name
4. expand boot from 5 → 10 daemons in dep-ordered launch
5. add SQL surface probe (3-row CSV ingest → COUNT(*)=3 assertion)
6. candidates corpus was synthetic SWE-tech (Swift/iOS, Scala/Spark) —
   wrong domain for staffing queries; replaced with ethereal_workers
   (10K rows, real staffing schema, "e-" id prefix to avoid collision
   with workers' "w-"). staffing_workers driver gains -index-name +
   -id-prefix flags so the same binary serves both corpora
7. local_judge qwen3.5:latest is a vision-SSM 256K-ctx build running
   ~30s per judge call against the lift loop; reverted to
   qwen2.5:latest (~1s/call, 30× faster, held lift theory)

Each contract drift (1, 3) is now locked into a cmd/<bin>/main_test.go
so future drift fires in `go test`, not in a reality run. R-005 closed:

- cmd/matrixd/main_test.go (new) — playbook record drift detector +
  score bounds + 6 routes mounted
- cmd/queryd/main_test.go — wrong-field-name drift detector
- cmd/pathwayd/main_test.go (new) — 9 routes + add round-trip + retire
- cmd/observerd/main_test.go (new) — 4 routes + invalid-op + unknown-mode

`go test ./cmd/{matrixd,queryd,pathwayd,observerd}` all green.

Reality test results (reports/reality-tests/playbook_lift_001.{json,md}):
  Queries              21 (staffing-domain, 7 categories)
  Discoveries          8 (judge ≠ cosine top-1)
  Lifts                7/8 (87.5%)
  Boosts triggered     9
  Mean Δ distance      -0.053 (warm closer than cold)
  OOD honesty          dental/RN/SWE rated 1, no fake matches
  Cross-corpus boosts  confirmed (e- ↔ w- swaps in lifts)
