fix: improve CodexLens env defaults, self-exclusion, and route handling

- Adjust env defaults (embed batch 64, workers 2) and add HNSW/chunking params
- Exclude .codexlens directory from indexing and file watching
- Expand codexlens-routes with improved validation and error handling
- Enhance integration tests for broader route coverage
