fix: replace bare except clauses with except Exception in ingest.py

[harshadkhetpal]

Summary

Replace 5 bare except: clauses with except Exception: in graphrag-ollama-config/ingest.py (lines 183, 236, 561, 642, 696). Bare excepts catch all exceptions including SystemExit, KeyboardInterrupt, and GeneratorExit, which should generally propagate.

Change:

# Before
except:
    pass

# After
except Exception:
    pass

Testing

No behavior change for normal exceptions — style/correctness fix per PEP 8.

[JiwaniZakir]

The change from bare except: to except Exception: is correct and prevents accidentally swallowing KeyboardInterrupt, SystemExit, and GeneratorExit. That said, several of these handlers could be narrowed further to improve debuggability — for example, the os.remove(log_path) call in trigger_graphrag_index_with_progress around line 642 realistically only needs to handle FileNotFoundError or PermissionError, and the pd.read_parquet calls (lines 561, 720, 838) could catch FileNotFoundError or pyarrow/fastparquet exceptions specifically. All of these except Exception: pass blocks silently discard errors with no logging, which makes diagnosing failures in production difficult — even a logging.debug(exc_info=True) would significantly improve observability. The get_last_run_id function is a good candidate for tighter handling since a failure there likely means the log file is malformed or missing, which are distinguishable and actionable conditions worth surfacing.
