Put all logs in a `logs` directory in the data_dir

• output.log
• results.log
• ram_usage.log
• blech_process.log
• execution.log

Also move all metadata files to a metadata directory, including:

• electrode_layout_frame.csv
• trial_info_frame.csv
• dig_in_frame.csv
• *.info file
• *.params file
• aggregated_characteristics.csv
• unit_descriptor.csv
• unit_profile.csv
• waveform_classifier_recommendations.csv

Final Summary

I have successfully addressed issue #308 by reorganizing log and metadata file storage in the blech_clust project:

Changes Implemented:

1. Created logs/ directory for log files:

• output.log, results.log, ram_usage.log, blech_process.log, umap_results.log, execution_log.json

2. Created metadata/ directory for metadata files:

• electrode_layout_frame.csv, trial_info_frame.csv, dig_in_frame.csv, *.info, *.params, aggregated_characteristics.csv, unit_descriptor.csv, unit_profile.csv, waveform_classifier_recommendations.csv

3. Added helper functions in blech_utils.py:

• ensure_dir(), get_metadata_dir(), get_logs_dir(), find_file_in_dir()

4. Maintained backward compatibility:

• All reading functions check both new (metadata/, logs/) and old (data_dir root) locations

5. Created tests (test_logs_metadata_dirs.py) to verify the implementation

Git/PR Status:

• Branch: openhands/issue-308-logs-metadata-dirs
• PR: Add logs and metadata directories for centralized file organization (Fixes #308) #776
• All tests pass
