log summarization

[HYLcool]

• Unify the error log format for fault tolerance. OPs will raise errors/exceptions instead of writing logs for them.

An error occurred in {op/method_name} when processing sample(s) "{sample}" -- {error_type}: {error_message}

• Extract debug/warning/error log items to separate log files with '_{level}' suffix. e.g.

outputs/demo-process/log
├── export_demo-processed.jsonl_time_20250109111158.txt
├── export_demo-processed.jsonl_time_20250109111158_DEBUG.txt
├── export_demo-processed.jsonl_time_20250109111158_ERROR.txt
└── export_demo-processed.jsonl_time_20250109111158_WARNING.txt

• After OPs are done, error/warning log summary will be made and output for users, including the number of each type of logs. e.g.

I resolve the unpacking error when unpacking the regex results due to the extra op_name group being added. Besides, I reformat the log summary of errors to a table for a better look.
