feat(hooks): phase-08 integration tests (A-F buckets)

27 test cases across 7 files exercising real PG + SQLite backends:
- A: tenant isolation (resolver scope, cross-tenant guard)
- B: sandbox escape + per-tenant fairness (goja hardening e2e)
- C: capability tier + FireResult propagation (source-tier gate)
- D: builtin seed reconciliation + idempotency + v21 rebuild
- E: command auto-disable migration (Standard vs Lite)
- F: WS method-equivalent (Validate, Create, TestRunner)
All green with -race on PG; D6 green on sqliteonly.
