Add a new "Row 2.5" to the overview tab between the trend chart and model/activity panels, showing two side-by-side live activity charts: - Today: 24-bar hourly token histogram with 12h-format labels (12a, 1a, ... 11p). Header shows total tokens consumed today. - Last Hour: 12-bar five-minute token histogram with relative-time labels (-55, -50, ... -5, now). Header shows tokens in the last 60 minutes. Both charts use BarChart with theme-colored bars (Blue for today, Accent for last hour) and adapt height in compact layouts. Helper functions hourLabels24() and minuteLabels() generate the X-axis label arrays. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
