fix: resolve CodexLens installation issues by correcting package name and improving local path detection

- Updated package name from `codexlens` to `codex-lens` in all relevant files to ensure consistency with `pyproject.toml`.
- Enhanced `findLocalPackagePath()` to always search for local paths, even when running from `node_modules`.
- Removed fallback logic for PyPI installation in several functions, providing clearer error messages for local installation failures.
- Added detailed documentation on installation steps and error handling for local development packages.
- Introduced a new summary document outlining the issues and fixes related to CodexLens installation.
