czlonkowski c1485d8f1b fix: resolve GitHub Actions workflow failures
## Fixed dependency updater workflow
- Added explicit workspace directory handling
- Improved error handling with clear error messages
- Fixed update summary file reading with error suppression
- Added error output for debugging failures

## Fixed Docker build workflow
- Added memory constraints (8GB/16GB swap) to prevent OOM
- Fixed Dockerfile to use npm scripts instead of direct node execution
- Added fallback mechanism: optimized rebuild → regular rebuild → error
- Added buildx ID reference and no-cache filter for db-builder stage

These changes should resolve both workflow failures and make the CI/CD pipeline more robust.
