Module transcript 

Transcript file parsing for Claude Code JSONL files.

This module parses Claude Code transcript files (JSONL format) to extract events as a third data source alongside hooks and OTEL.

Key advantages over OTEL:

• is_sidechain field: distinguishes main chain from subagent requests
• Full content: prompt text, response text, tool I/O
• parent_uuid: enables conversation tree reconstruction
