guise: install-hook

Install a native git pre-push hook that enforces this repo's account in every terminal — not just inside a Claude session. The hook runs 'guise use' and 'guise validate' before each push and aborts on mismatch. Use when the user wants pushes to always go through the correct account even from a plain shell, or after another terminal ran 'gh auth switch'.

guise: install-hook

The Claude Code PreToolUse hook only sees commands run inside a Claude session. A developer pushing from their own terminal — after a gh auth switch somewhere else — bypasses guise entirely. This installs a native git pre-push hook so the repo's account is forced before every push, from any terminal.

"${CLAUDE_PLUGIN_ROOT}"/scripts/run.sh install-hook

The hook runs guise use (GitHub: gh auth switch · Bitbucket/GitLab: pin the SSH key) then guise validate, and aborts the push if the account can't be made correct.
It never clobbers an existing non-guise pre-push hook — it reports and stops.
Remove it with "${CLAUDE_PLUGIN_ROOT}"/scripts/run.sh uninstall-hook.
