HYDI-36: Phase 5: Postgres integration tests for db/queries.ts (opt-in)

[kasperwelner]

Implements HYDI-36

Changes

• Added an opt-in integration suite at src/db/queries.integration.test.ts that executes src/db/schema.sql and validates SQL-heavy behavior in src/db/queries.ts:
  • upsertDispatchRun insert + ON CONFLICT summary preservation via COALESCE
  • removeBlocker array removal behavior, including last-blocker transition to queued from blocked_cycle
  • updateRunStatus partial update behavior and null-vs-undefined semantics (blocked_by clears on null, pr_url unchanged on null)
  • getRunsBlockedBy array containment and getActiveRunCount
  • Additional integration coverage for project config lookups and list/delete helpers
• Added scripts/test-db.sh and wired npm run test:db:
  • Uses disposable Docker Postgres on port 5433 when Docker is available
  • Falls back to in-process PGlite when Docker is unavailable, while preserving query-level integration assertions
• Updated vitest.config.ts include globs to recognize *.integration.test.ts
• Updated docs/testing.md with a new DB integration test section (gating, invocation, fallback mode, and semantic examples)

Validation

• npm test (integration tests skipped cleanly by default)
• npm run test:db
• RUN_DB_TESTS=1 TEST_DB_MODE=pglite ... npm run test:coverage -- --testNamePattern integration
  • src/db/queries.ts coverage: 100% statements
• npm run typecheck
