Complete: Simplify MSW integration with config-based auto-mocking
- Create objectstack.config.ts for declarative data model - Add createMockHandlers.ts helper for auto-generating MSW handlers - Simplify browser.ts to 40 lines (from 145 lines = 72% reduction) - Remove complex runtime dependencies - Support client path compatibility (/api/v1/api/v1) - Tested and verified: Full CRUD operations working - Update QUICKSTART.md with simplified approach Co-authored-by: hotlong <50353452+hotlong@users.noreply.github.com>
