Improve gather_result, remove filter, fix inf loop in truncation

[xingdi-eric-yuan]

This pull request introduces several changes across multiple files, focusing on enhancing the analysis of agent behavior, simplifying the codebase, and removing obsolete functionality. The most significant updates include modifications to the analysis/gather_results.py file to improve data grouping and path extraction, the removal of the entire trajectory filtering module, and the addition of a new error handling case in the debug_gym environment.

Enhancements to analysis/gather_results.py:

• Removed the map_uuid function, simplifying the handling of UUIDs.
• Added logic to extract relative paths from log file paths and include them in the results dictionary.
• Updated the data grouping logic to include the path field, enabling finer-grained analysis.
• Enhanced success rate reporting to include the path and uuid in the output.

Removal of trajectory filtering module:

• Deleted the README.md file for trajectory filtering, removing documentation for the module.
• Removed the criteria.py file, which contained various filtering criteria for analyzing trajectories.
• Deleted the filter.py file, which implemented trajectory filtering logic and command-line tools.

Updates to debug_gym environment:

• Added a new error handling case in get_triggered_tools to return a descriptive message when no tool call is generated by the agent.
• fixed inf loop issue in message truncation, added test cases.
