When a repo has no parseable files (e.g., unsupported languages or all
files filtered out), chunks.reduce returns 0, causing createASTCache(0)
to pass max:0 to LRUCache which throws TypeError. This clamps maxSize
to at least 1 and adds a progress message when no parseable files exist.
- 59 test files covering unit and integration tests
- vitest config with coverage thresholds and fork pooling
- Test fixtures (mini-repo + multi-language sample code)
- Add vitest + coverage-v8 to devDependencies
- Add test scripts (test, test:integration, test:all, test:watch, test:coverage)
- Move typescript to devDependencies where it belongs
