DuckDB has used WAL by default since v0.8, so this pragma is not valid DuckDB syntax. Removed obsolete try-except block that attempted to enable WAL on system database initialization.
Major additions: - Web UI: Jinja2 templates in FastAPI (login, dashboard, catalog, corporate memory, admin) - API: catalog profiles/metrics, telegram verify/unlink/status, admin table registry CRUD - Corporate memory governance: approve/reject/mandate/revoke/edit/batch + audit log - Sync: real DataSyncManager trigger, sync-settings, table-subscriptions - CLI: setup (init/test/deploy/verify), server (logs/restart/deploy/backup), explore - Instance config integration (instance.yaml loaded at startup) - 140 tests passing (25 new)
