Head-to-Head bar charts, Working Style, and Context.
Planning rate now detects TaskCreate/TaskUpdate/TodoWrite instead of
only EnterPlanMode (which was never used, showing 0% for all models).
Validated against raw JSONL with zero false positives.
Responsive side-by-side layout at 90+ cols. Self-correction scanner
with compact file skipping and model+timestamp dedup. 274 tests.
Remove high-false-positive patterns (I'm sorry, I should have, sorry for).
Add precise patterns (you're right I, that was incorrect, let me correct).
Skip compact JSONL files that replay compressed context.
Deduplicate by model+timestamp to prevent double-counting.
Fix test timestamps to work with deduplication.
Adds scanSelfCorrections() which reads raw .jsonl session files (including subagent dirs) and counts per-model self-correction patterns for use in the model comparison metrics.
