fix: replace bare except with except Exception in shared.py

[harshadkhetpal]

Summary

Replace bare except: with except Exception: in utils/shared.py.

PEP 8 recommends against bare except: — it should specify an exception type. Since this catch block handles an error without re-raising (prints and falls back to empty dict), except Exception: is the correct replacement.

Change:

# Before
try:
    with open(cache_path, "r", encoding="utf8") as file:
        cache_data = json.load(file)
except:
    print(f'cached file {cache_path} is invalid')
    cache_data = {}

# After
except Exception:
    print(f'cached file {cache_path} is invalid')
    cache_data = {}

Testing

No behavior change — style/correctness fix only. Using except Exception: avoids catching SystemExit, KeyboardInterrupt, etc.
