Extract token metrics from the context_window object provided by Claude Code v2.0.65+ instead of parsing transcript JSONL files. This provides more accurate and faster context percentage calculations. - Add input-parsers.ts utility with extractTokenMetricsFromContextWindow() - Update ContextPercentage and ContextPercentageUsable widgets to use new data - Fall back to JSONL parsing when context_window is not available - Update types to include context_window in StatusJSON Closes sirmalloc#126 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
