google_chat.md still routed --install-deps through tools.lazy_deps and
HERMES_LAZY_INSTALL_TARGET; the plugin calls pm.sync_venv and the Docker
venv is read-only. windows-native.md named hermes_cli/dep_ensure.py and
install.ps1 -Ensure, neither of which exists; features call pm.ensure.
desktop.md and updating.md promised an automatic corrupt-zip retry and
npmmirror fallback for the Electron download; build_prepared_desktop runs
the build once and a failed product aborts the update, so document the
manual recovery (clear the @electron/get cache, set ELECTRON_MIRROR,
rebuild) instead.
