Add CodeQL, Dependabot, pnpm audit, and automated releases

- CodeQL: JS/TS static analysis on push, PRs, and weekly schedule
- Dependabot: weekly npm + GitHub Actions dependency updates
- pnpm audit: production dependency CVE check in CI
- Release workflow: auto-creates GitHub release + tag on version bumps
- Enabled secret scanning + push protection on the repo
