## Title

    Proposed fix: [micropip] 'Cannot install <req>: micropip only installs prebuilt wheels and does not support installing from a VCS URL (git+, hg+, svn+, bzr+)' / 'Requested <req>, but <pkg>==<v> is alr

## Body

    Recommended action: Install from a wheel URL or index name instead of git+; pass reinstall=True (or micropip.uninstall first) to change versions; check the package name and index_urls.
    
    Option: Install from a wheel URL or index name instead of git+; pass reinstall=True (or micropip.uninstall first) to change versions; check the package name and index_urls. [evidence: official_recommended_action]
    Applies when: Agents porting pip commands (git+https URLs, version pins) to micropip in Pyodide
    Steps:
    1. Build a wheel from the repo and host it; micropip.install('<wheel url>').
    2. await micropip.install('pkg==x.y', reinstall=True)
    3. Verify micropip.set_index_urls / index_urls.
    Expected: The error no longer appears.
