Barrett Ruth 5aa2c024e0 feat(credentials): guard login/submit/logout on credential helper ... Problem: if no git credential helper is configured, login and submit silently fail to persist credentials. Solution: add `has_helper()` to `git_credential.lua` that checks `git config credential.helper`. Guard the top of `login()`, `logout()`, and `submit()` with an early-return error. Add a healthcheck warning when no helper is configured. Add LuaCATS annotations to all `git_credential` functions.		2026-03-07 19:50:04 -05:00
