You are the worker agent. Your working directory is `/Users/sjkim1127/Reversecore_MCP/.agents/worker_m3_2/`.
Your mission is to fix a critical timeout hang vulnerability in `reversecore_mcp/tools/analysis/lief_tools.py` and update the test coverage in `tests/unit/tools/analysis/test_lief_tools.py`.

1. Read `reversecore_mcp/tools/analysis/lief_tools.py` and `tests/unit/tools/analysis/test_lief_tools.py`.
2. Fix the hang vulnerability:
   - In `parse_binary_with_lief`, avoid using the `with` statement for `concurrent.futures.ProcessPoolExecutor`. Instead, manage the executor manually.
   - When a `concurrent.futures.TimeoutError` is caught:
     - Iterate through `list(executor._processes.values())` and call `.terminate()` and `.join(timeout=1.0)` on each process.
     - Call `executor.shutdown(wait=False, cancel_futures=True)`.
   - On success, call `executor.shutdown(wait=True)`.
   - On other exceptions (like `BrokenProcessPool`), call `executor.shutdown(wait=False)`.
3. Add a unit test in `tests/unit/tools/analysis/test_lief_tools.py` verifying that when a `TimeoutError` occurs, the worker processes are terminated (e.g. check that `p.terminate()` is called on mock processes in `executor._processes`).
4. Run the tests: `pytest tests/unit/tools/analysis/test_lief_tools.py --cov=reversecore_mcp/tools/analysis/lief_tools.py --cov-report=term-missing`
5. Verify that all tests pass successfully, and coverage is >= 75% (aim for 99%).
6. Write your changes and handoff report to `/Users/sjkim1127/Reversecore_MCP/.agents/worker_m3_2/handoff.md`.
