fix: Restore drizzle-kit generate by syncing snapshot baseline

Snapshots were stale since migration 0008. Generated a schema-derived
snapshot at 0032 so drizzle-kit generate works again (zero diff on
current schema.ts). Also fixed migration 0032 to use statement-breakpoint
separator required by better-sqlite3.

- Added 0032_snapshot.json derived from current schema.ts
- Fixed 0032 SQL to use --> statement-breakpoint between statements
- Updated CLAUDE.md and database-migrations.md with correct workflow

 ## Key Rules
 
-- **Database migrations**: Hand-write SQL in `apps/server/drizzle/NNNN_name.sql` AND register it in `apps/server/drizzle/meta/_journal.json` (increment `idx`, set `tag` to filename without `.sql`). Both files must be committed together. Do NOT use `drizzle-kit generate` — snapshots are stale since migration 0008. See [docs/database-migrations.md](docs/database-migrations.md).
+- **Database migrations**: Edit `apps/server/db/schema.ts`, then run `npx drizzle-kit generate`. Multi-statement migrations need `--> statement-breakpoint` between statements. See [docs/database-migrations.md](docs/database-migrations.md).
 - **Logging**: Use `createModuleLogger()` from `apps/server/logger/index.ts`. Keep `console.log` for CLI user-facing output only.
 - **Hexagonal architecture**: Repository ports in `apps/server/db/repositories/*.ts`, Drizzle adapters in `apps/server/db/repositories/drizzle/*.ts`. All re-exported from `apps/server/db/index.ts`.
 - **tRPC context**: Optional repos accessed via `require*Repository()` helpers in `apps/server/trpc/routers/_helpers.ts`.
