Fix bare except blocks catching BaseException in WebSocket handler

[Copilot]

Addresses code review feedback on PR #3 regarding improper exception handling in the WebSocket endpoint.

Changes

• Replace bare except: with except Exception: in WebSocket error handler

The bare except: block was catching BaseException, which includes system exceptions like KeyboardInterrupt and SystemExit that should propagate normally.

# Before
try:
    await websocket.close(code=status.WS_1011_INTERNAL_ERROR)
except:
    pass

# After
try:
    await websocket.close(code=status.WS_1011_INTERNAL_ERROR)
except Exception:
    pass
