v1.18: center the tank + driver in the launcher icon

The subject was filling the frame edge-to-edge, so launcher masking
clipped the gun barrel, treads, and the driver. Auto-detect the tank+bot
(erode away the debris specks, take that bbox), recenter on a square
canvas at ~74% with matching navy #0B1D27 margin so the whole subject
stays inside any mask shape. Regenerated all densities + icon.png.

 - **SESSION** bar — current 5-hour window utilization with reset time
 - **WEEKLY** bar — 7-day rolling usage with reset time
+- **Pace marker** — a colored tick on each bar shows where you *should be* right now to finish at
+  exactly 100% by reset. Tick color grades your projection: green (way under budget) → teal →
+  yellow → orange → red → purple (burning way too fast), with an "X% over/under pace" label.
+- **Peak-hours indicator** — a Claude burst icon that lights up 🔥 during Anthropic's peak window
+  (5–11 AM Pacific, Mon–Fri), when tokens burn faster, with a countdown to the window close.
+- **Usage history chart** — the app plots your session and weekly utilization over the past 7 days,
+  so you can see your consumption trend, not just the current snapshot.
+- **Usage alerts** — opt-in notifications when session or weekly usage crosses a threshold you set
+  (sliders, 50–100%). Each alert fires at most once per limit window, so you're never spammed.
 - Tap the widget to open the app; tap ⟳ to force-refresh
 - Responsive: works as 4×1 (compact) or 4×2 (full)
 - Auto-refreshes every 5 minutes in the background
