chore: consolidate configs and optimize test execution

Consolidate configuration files and optimize test performance:
- Remove orphaned config files (isolated-tests.json, test/data/.editorconfig)
- Unify vitest coverage thresholds to 100% across all configs
- Consolidate coverage exclude patterns between configs
- Enhance .gitignore with missing patterns (*.log, *.pid, *.seed, *.pid.lock)
- Optimize slow tests: 1MB JSON generation and infinite loop detection
- Update CI workflow SHA to latest version (e7f70a7e)

Test execution improved from 3.85s to 1.08s (72% faster).

 ### Testing
 
+**Vitest Configuration**: This repo uses the shared vitest configuration patterns documented in `../socket-registry/CLAUDE.md` (see "Vitest Configuration Variants" section). Three configs available:
+- `.config/vitest.config.mts` - Main config (default)
+- `.config/vitest.config.isolated.mts` - Full process isolation for vi.doMock()
+
 #### Test Structure
 - **Test files**: `test/` - All test files
 - **Spec compliance**: `test/purl-spec.test.mts` - Package URL spec tests
