 ### Added
 - **Monthly cost in the status bar** — the `statusBarMetric` setting gains a
   new `monthly-cost` option. When selected, the first status-bar item shows the
   current calendar month's total cost ($(calendar) icon) instead of today's
   cost. Hover tooltip mirrors the today tooltip with month-to-date token and

 - **Sessions: resume / copy / delete** — each session row can copy its id, copy
   its project path, resume it (in the
   official Claude Code extension, or a terminal for cross-project sessions), or
   delete it (to the trash, after a confirm); plus a Current project / All filter.

 - **Quota display options** — `quotaFiveHourOnly` (show only the 5-hour window)
   and `showResetInStatusBar` (append a compact reset countdown) in the ⚙ Settings
   tab. The default stays the clean `5h 6% · wk 1%`; full reset times always live

+- **Account switch now refreshes the quota** — switching Claude accounts no
