Add run dashboards, historical reports, and mobile dashboard UX

[MaTriXy]

Summary

• add HTML run dashboard generation and per-run tracking
• add on-demand report delivery in Telegram
• add historical run import from Claude logs for past runs
• improve dashboard usability on mobile browsers (menu drawer, touch flow area, bottom detail panel)
• document run-report features and command usage in README

Bot Commands Added

• /report
  Sends an HTML dashboard for the latest tracked run in the current session.

• /report <runIdPrefix>
  Sends the report for a specific tracked run by ID prefix.

• /reporthistory <projectPath>
  Loads historical runs from ~/.claude/projects/... and sends the latest Babysitter run report.

• /reporthistory <projectPath> --index N
  Chooses older historical runs (1 is latest).

• /reporthistory <projectPath> --session <sessionIdPrefix>
  Filters historical runs to a specific Claude session.

• /reporthistory <projectPath> --all
  Includes non-Babysitter runs in historical lookup.

Technical Notes

• Telegram file send uses a temporary HTML file that is removed after upload.
• Optional persistent local previews can be saved via RUN_REPORTS_PREVIEW_DIR.
• Historical parsing normalizes project paths and supports quoted command arguments.

Validation

• npm run build
• npm test -- --runInBand
