feat(test): add PostgreSQL migration slow integration tests (G-003)

Browse Source 
- Add tests/integration/persistence/test_migrations_postgres.py
- All tests marked with @pytest.mark.slow
- Tests skip when TEST_POSTGRES_URL is not set (no local PostgreSQL)
- Database isolation via clean_tables and clean_alembic_version fixtures
- Update CI workflow to use pytest instead of inline Python script
- Remove TODO(G-003) comment
- Update tests/README.md with PostgreSQL test documentation

Covered scenarios:
- Baseline stamp sets revision
- Upgrade from baseline to head
- Upgrade idempotent
- Get current on unstamped DB returns None

@@ -244,8 +244,27 @@ SQLite migration tests can be run locally without any external dependencies:
uv run pytest tests/integration/persistence/test_migrations.py -q --tb=short
```
CI workflow `.github/workflows/test-migrations.yml` runs SQLite tests using pytest.
PostgreSQL migration tests still use inline Python script (will be migrated to pytest in G-003).
PostgreSQL migration tests require an external PostgreSQL database:
```bash
# PostgreSQL migration tests (requires PostgreSQL service)
# Tests are marked as slow and skipped if TEST_POSTGRES_URL is not set
TEST_POSTGRES_URL=postgresql+asyncpg://user:pass@localhost:5432/test_db \
uv run pytest tests/integration/persistence/test_migrations_postgres.py -q --tb=short
# Or skip by default (no PostgreSQL available)
uv run pytest tests/integration/persistence/test_migrations_postgres.py -q --tb=short
# Output: SKIPPED (TEST_POSTGRES_URL not set)
```
Note: PostgreSQL tests are **not** included in fast integration gate because they:
- Require external PostgreSQL service
- Are marked with `@pytest.mark.slow`
- Need `TEST_POSTGRES_URL` environment variable
CI workflow `.github/workflows/test-migrations.yml` runs:
- SQLite tests in `test-migrations-sqlite` job (fast, no external services)
- PostgreSQL tests in `test-migrations-postgres` job (uses PostgreSQL service container)
