Standalone script that scans Claude Code, Codex CLI, and Gemini CLI
session directories, resolves each session's working directory to a git
repo, deduplicates by normalized remote URL, and outputs structured JSON.
- Reads only first 4-8KB of session files (avoids OOM on large transcripts)
- Only counts JSONL files modified within the time window (accurate counts)
- Week windows midnight-aligned like day windows for consistency
- 16 tests covering URL normalization, CLI behavior, and output structure
