Andy Lee 490329dc66 fix: clean and simple hang prevention solution
This commit provides a minimal, focused fix for CI hanging issues by addressing the root causes:

**Key Changes:**

1. **ZMQ Resource Management:**
   - Remove `context.term()` calls that were causing hangs
   - Add `socket.setsockopt(zmq.LINGER, 0)` to prevent blocking on close
   - Keep socket operations simple with default timeouts (no artificial limits)

2. **Process Cleanup:**
   - Add timeout (1s) to final `process.wait()` in embedding server manager
   - Prevent infinite waiting that was causing CI hangs

3. **Resource Cleanup Methods:**
   - Add simple `cleanup()` methods to searchers and API classes
   - Focus on C++ object destruction for DiskANN backend
   - Avoid complex cleanup logic that could introduce new issues

4. **Basic Test Safety:**
   - Simple pytest-timeout configuration (300s)
   - Basic test session cleanup using psutil
   - Minimal conftest.py without complex logic

**Philosophy:**
This solution avoids the complex multi-layered fixes from the previous PR chain.
Instead, it targets the specific root causes:
- ZMQ context termination blocking
- Process wait() without timeout
- C++ resource leaks in backends
