Enables issue analysis workflow to trigger on comments posted to pull requests. This is done by removing the `!github.event.issue.pull_request` check from the GHA issue analysis workflow definition, since GitHub models PR comments under the `issue_comment` event. The fix implementation workflow remains restricted to issues to prevent PR-on-PR loops and permission issues.
- Update scripts/run_antigravity.py to include comments and review comments in JSON payloads fetched by helper tools.
- Update adk-issue and adk-issue-analyze skills to prevent routing conflicts when /adk-issue-analyze is explicitly requested.
- Update branch validation in issue-fix workflow to fail if the agent does not successfully create and checkout fix/issue-<number>.
- Update adk-issue-fix skill branch template to match expected GHA workflow fallback pattern.
