Automated vulnerability triage and dependency bumps for the git_integration worker (Python via uv + the two vendored Go modules). Fetches open Dependabot alerts scoped to git_integration manifests, correlates them with open Dependabot PRs, classifies each fix as safe or needs-human, validates safe fixes locally on the PR branches merged with latest main (uv sync / lint / pytest + full git-integration image build, which compiles both Go modules), updates safe PR branches server-side so they are one click from merge, then posts a "safe to merge" review summary to Slack and opens PRs for alerts Dependabot has no PR for. NEVER merges PRs, never dismisses alerts, never deploys without explicit user confirmation. Use when the user says "fix vulns", "bump deps", "dependabot triage", or asks about git_integration vulnerabilities.
