Rename the v2 search engine package to `codexlens-search` (import as `codexlens_search`) so it can be installed independently and consumed by the original codex-lens as a dependency. This avoids package path conflicts since both previously used `src/codexlens/`. Changes: - Rename src/codexlens/ -> src/codexlens_search/ - Update pyproject.toml: name=codexlens-search, version=0.2.0 - Update all imports across source, tests, and scripts - Add public API exports in __init__.py (Config, SearchPipeline, IndexingPipeline, SearchResult, IndexStats) 37/37 tests pass. No functional changes. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
