feat(14-03): implement SwaggerSource and DeployPreviewSource with tests

- SwaggerSource probes OpenAPI doc endpoints for API keys in example/default fields - DeployPreviewSource scans Vercel/Netlify preview URLs for __NEXT_DATA__ env leaks - Both implement ReconSource, credentialless, with httptest-based tests
