Pull request overview

This PR adds a GITHUB_ACTION_MODE feature that allows safe-settings to post PR comments using GitHub Actions' built-in environment variables (GITHUB_REPOSITORY, GITHUB_REF) instead of relying on the existing CREATE_PR_COMMENT + check-suite payload flow.

Changes:

Adds GITHUB_ACTION_MODE, GITHUB_REPOSITORY, and GITHUB_REF to lib/env.js
Extracts the summary template outside the CREATE_PR_COMMENT conditional block and adds a new code path in handleResults that posts PR comments using GitHub Actions env vars
Documents the new action mode in docs/github-action.md
