* chore: implement ESM standardization and security attestation
Aligning root infrastructure with Node.js v24.14.0 standards.
- Set type: module in package.json to eliminate re-parsing overhead.
- Migrated Jetski Loader tests to .cjs to maintain legacy security audit compatibility.
- Verified path traversal and symlink protections with clean attestation.
* chore(ci): update pr_preflight path to .cjs for ESM compatibility
* feat(infra): surgical ESM modernization for Gemini suite
Resolved Codex P1 by reverting global root ESM shift to preserve installer stability.
- Implemented scoped 'type: module' in /docs/integrations/jetski-gemini-loader/ to eliminate re-parsing overhead.
- Updated test runner (run-test-suite.js) and CI (ci.yml) to track .cjs transitions.
- Verified zero-warning execution in Node v24.14.0.
