fix: tighten exception handling in daemon.py, soulful_core.py, zhiyi/__init__.py

- daemon.py: replace bare 'except Exception: pass' with specific
  (json.JSONDecodeError, OSError, IOError, KeyError, TypeError) in
  save_llm_context() — all 4 locations
- soulful_core.py: replace bare Exception in _zhiyi_commit with
  (requests.exceptions.Timeout, ConnectionError, RequestException, OSError, IOError);
  note ZHIYI_TIMEOUT=3 kept unchanged
- zhiyi/__init__.py: replace bare Exception in _load_soulful_context with
  (json.JSONDecodeError, OSError, IOError, KeyError, TypeError)

All files verified: python3 -m py_compile OK
