Subject: [PATCH 1/3] ci: add GitHub Actions workflow for PRs

Runs on pull_request into main: pre-commit (--all-files), a Python compile check, and a hermetic installer dry-run (stubs the ferrosa-memory turn-hook helper and writes to a temp dir). PR-only because pre-commit's no-commit-to-branch hook fails on main by design.

Subject: [PATCH 3/3] ci: skip bandit checks for documented intentional
 patterns

B310 (raw-urllib MCP client), B404/B603 (installer's fixed verification subprocess), B110 (fail-open config load) are intentional per CLAUDE.md. A stale local pre-commit venv masked these; pinning the skip list makes bandit deterministic in CI.
