This replaces the previous manual JSON file system with standard Drizzle migrations, enabling: - Proper database schema migrations with timestamp-based versioning - Batched migration for faster migration of large datasets - Better data integrity with proper table schemas instead of JSON blobs - Easier database upgrades and rollback capabilities Migration changes: - Todo table now uses individual columns with composite PK instead of JSON blob - Share table removes unused download share data - Session diff table moved from database table to file storage - All migrations now use proper Drizzle format with per-folder layout Users will see a one-time migration on next run that migrates existing JSON data to the new SQLite database.

## Database
|
|
|
|
- **Schema**: Drizzle schema lives in `src/**/*.sql.ts`.
|
|
- **Naming**: tables and columns use snake*case; join columns are `<entity>_id`; indexes are `<table>*<column>\_idx`.
|
|
- **Migrations**: generated by Drizzle Kit using `drizzle.config.ts` (schema: `./src/**/*.sql.ts`, output: `./migration`).
|
|
- **Command**: `bun run db generate --name <slug>`.
|
|
- **Output**: creates `migration/<timestamp>_<slug>/migration.sql` and `snapshot.json`.
|
|
- **Tests**: migration tests should read the per-folder layout (no `_journal.json`).
