- Remove gap_days_to_end and last_trade_close from analyze_report output
- Add idle_time: total backtest duration minus all position holding times
(includes flat time before first trade and after last trade)
- Add format_duration() helper for timedelta -> HH:MM:SS formatting
- Parse both start/end dates from period string for accurate calculation
- Update print_report() to display idle_time in Holding Times section
- main() now always computes analyze data for text report
- Update AGENTS.md: add scripts docs, jobs/resources dirs, verification method
Period format is "H4 (2024.12.25 - 2026.06.22)" — use regex to extract
the date before the closing paren instead of split+strip which fails on
the trailing ")".
Parse end date from Settings.period ("2024.01.01 - 2025.06.22") and use
it as reference for gap_days. Falls back to datetime.now() only if period
cannot be parsed. Rename output key gap_days_to_now → gap_days_to_end.
