FN-9148: add PostgreSQL loaded-failure census
Add retained-log census tooling and evidence for PostgreSQL loaded-lane timeout investigations.
- Parse complete Vitest logs and optional diagnostics without opening PostgreSQL or running tests.
- Classify failing files, lifecycle positions, failure shapes, backend headroom, waits, and watchdog data.
- Cover high-failure, healthy, malformed-diagnostics, and truncated-log cases with fixtures.
- Document the reproduced population, unsupported remedies, and successor measurement requirements.
