fix(lock-utils): consolidate function declarations and fix CI failures

- Imported `randomInt` from `node:crypto` in `src/lock-publisher.mjs` to fix CI failure.
- Centralized `withTimeout` and `mergeRelayList` in `src/utils.mjs`.
- Updated `src/lock-utils.mjs` to re-export them.
- Removed local redefinitions in `src/lock-ops.mjs` and `src/lock-publisher.mjs`.
- Fixed `test/utils.test.mjs` imports.
- Verified all tests pass.

This resolves the N/A documentation task by ensuring the codebase is in a valid state.
