fix: replace bare except with json.JSONDecodeError in trajectory parser

[nuthalapativarun]

Summary

• Replace a bare except: clause with except json.JSONDecodeError: in the trajectory parser's evaluation log loader

Changes

• ufo/trajectory/parser.py: narrow the exception catch in _load_evaluation_data from bare except to json.JSONDecodeError — the only error json.load raises for malformed input; a bare except would silently swallow unrelated errors (e.g. IOError, PermissionError) and hide data corruption issues

No open issue — identified as a code quality improvement in ufo/trajectory/parser.py.
