refactor: rename exportName to name across entire codebase

- Database: Migrate column export_name to name in tools table
- Prisma schema: Update Tool model to use name field
- Sync routes: Update keyword and changes sync to use name
- Railway executor: Update API endpoints to use name parameter
- API routes: Update all tool routes to use name field
- Web app: Update all pages and components
- Playground: Update tool loader and sidebar
- create-basic-tools: Update types and generators
- Scripts: Update sync and test scripts

Database migration was done via direct SQL:
  ALTER TABLE tools RENAME COLUMN export_name TO name;

The unique constraint remains on (package_id, name).
