name	Fix pre-existing linting errors in gitlab_context.py
description	plugins/gitlab-skill/skills/gitlab-skill/scripts/gitlab_context.py has 3 linting errors: PLC0415 x2 (deferred imports inside functions) and S607 (partial executable path in subprocess). Fix: move imports to top-level, use shutil.which() for glab path resolution. Same pattern was applied in fetch_gitlab_mr.py migration.
