fix(security): prevent command injection in governance service and fix build errors

- Mitigate command injection in `src/services/governance/index.js` by using explicit array arguments with `execFileSync` and adding a security comment.
- Add regression test `test/governance-security.test.mjs` verifying the fix against simulated exploit attempts.
- Fix CI build failures by resolving circular dependencies and duplicate declarations in `src/lock-utils.mjs`, `src/lock-ops.mjs`, `src/lock-publisher.mjs`, and `src/relay-health.mjs`.
- Resolve linting errors in tests and implementation files.
