        pyproject dependencies — everything Hermes fetches/launches is pinned
        to an exact version.

        - git installs must pin a full 40-char commit SHA (branches and tags
          can be moved by the upstream owner; SHAs cannot).
        - package-launcher stdio transports (uvx/npx and their pkg-manager
          equivalents) must carry an exact version specifier on the package
          arg (``pkg==X`` for Python, ``pkg@X`` for npm).

        http transports and ${INSTALL_DIR}-anchored commands have nothing to
        pin at the transport layer (the server runs elsewhere / comes from the
        SHA-pinned clone), so they're exempt.
