Updated sql_select, sql_update, and sql_delete to use explicit 'is not None' checks for record_id. This prevents falsy ID values (like 0) from triggering generic table scans or failing to filter, which was causing the config bootstrap to accidentally load record ID 1 when ID 0 was requested.
- Combined 10+ one-off tests into 4 primary functional suites (Search, Auth, Lifecycle, Vision).
- Archived original scripts to tests/archive/.
- Updated README with the new standardized inventory.
- Applied clean output formatting across the new suite.
- Moved legacy/redundant tests to tests/archive/.
- Relocated root-level debug scripts to tests/integration/.
- Updated tests/README.md with final organized inventory.
- Cleaned up root directory from one-off reproduction scripts.
