## Summary - Adds `isUnique?: boolean` to `RegularFieldManifest` in `twenty-shared`, allowing SDK applications to declare unique constraints on fields - Updates the manifest-to-flat-field converter to read `isUnique` from the manifest instead of hardcoding `false` - Generates corresponding unique index metadata in `computeApplicationManifestAllUniversalFlatEntityMaps` when a field has `isUnique: true`, matching the behavior of the `CreateFieldInput` path - Adds SDK-side validation rejecting `isUnique` on RELATION, MORPH_RELATION, and FILES field types - Adds integration test verifying manifest sync creates a unique index for `isUnique` fields - Adds SDK unit tests for `isUnique` validation on unsupported field types ## Test plan - [x] SDK unit tests: `defineField` accepts `isUnique: true` on TEXT, rejects on RELATION and FILES - [ ] Integration test: manifest sync with `isUnique: true` creates the unique index in DB - [ ] Verify `isUnique` defaults to `false` when not specified (backward compatible) - [ ] Verify standalone manifest fields (not nested in objects) also generate unique indexes correctly

Why Twenty
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
