## Summary
Implements the foundation for dynamic search field configuration from
[issue #1428](https://github.com/twentyhq/core-team-issues/issues/1428).
## Changes
- Add `SearchFieldMetadataEntity` junction table for storing searchable
field configurations
- Add `SearchFieldMetadataService` with core CRUD operations
- Add `SearchFieldMetadataModule` following existing patterns
- Add `IS_DYNAMIC_SEARCH_FIELDS_ENABLED` feature flag (defaults to
`false`)
- Database migration with proper indexes and foreign keys
## Architecture
Uses a junction table where **record existence = field is searchable**:
**Table: `searchFieldMetadata(objectMetadataId, fieldMetadataId,
workspaceId)`**
- Unique constraint on `(objectMetadataId, fieldMetadataId)`
- `ON DELETE CASCADE` on foreign keys
## Testing
- [x] Migration runs successfully
- [x] Table created with correct schema
- [x] Feature flag seeded properly
- [x] Database reset works correctly
## Next Steps
Future PRs will handle:
- Data migration from existing hardcoded search field configs
- Integration with search services
✅ No breaking changes — fully backward compatible.
