gh-init

The user wants to verify forge auth (or wants instructions to log in).

Run /gh-init. It detects the forge from the origin remote (defaulting to GitHub): on a GitHub repo it verifies gh auth + scopes; on a Bitbucket repo it checks the himmel bitbucket CLI auth (BITBUCKET_EMAIL + BITBUCKET_API_TOKEN) instead of gh OAuth scopes.

Output the single one-line summary the slash command prints. If it exits non-zero with gh NOT logged in, tell the user to run gh auth login --web from their own terminal — that flow is interactive (browser) and cannot be automated. If it exits non-zero with bitbucket NOT authenticated, tell the user to set BITBUCKET_EMAIL + BITBUCKET_API_TOKEN.
