fix: configure separate test script for Worker tests

- Exclude workers/** from main Vitest config to prevent module resolution errors
- Add test:worker script to run Worker tests with their dedicated config
- Update test:all to include Worker tests in the full test suite
- Worker tests now run correctly with Cloudflare Workers pool

Worker tests: ✅ 15 passed (15)
Main app tests: ✅ 160 passed, 1 skipped (161)

The Worker tests use @cloudflare/vitest-pool-workers which requires
a separate Vitest config. This change keeps Worker tests isolated
while still allowing them to run as part of the full test suite.
