v1.11: pace markers + peak-hours burst icon

Add a pace tick to each usage bar showing where you should be to finish
at 100% by reset, color-coded by projected tier, plus a Claude burst icon
that lights up during Anthropic peak hours (5-11 AM PT, Mon-Fri). Bars now
rendered as bitmaps so the same renderer drives both the widget and the app.

New: PaceCalc, PeakHours, BarRenderer, ic_claude_burst drawable.
versionCode 12 / versionName 1.11. Includes rebuilt signed release APK.
