fix: exclude db tests from workspace root and fix TS build errors

- Exclude src/db/tests from workspace vitest config (needs test DB)
- Make global-setup.ts gracefully skip when test DB unavailable
- Fix exactOptionalPropertyTypes issues in proxymodel-endpoint.ts
- Use proper ProxyModelPlugin type for getPluginHooks function
