Device Below Minspec Modal (Android)

## **⚠️ Problem:**
Play device exclusion (#2738) blocks new installs, not existing ones — devices under the <25 chipset cut keep the app and keep hitting unplayable fps + launch crashes. Those users leave 1-star reviews, dragging store rating → New Users; install base on that device set not yet baselined (#2738).

## **🏁 Scope:**
Android launch-time chipset detection against the #2738 excluded list → informational "device below minspec" modal. Heads-up only: no download link, no alternate distribution channel, no store redirect. Android only — iOS keeps the #1801 / #1825 behavior.

## **📝 Deliverables:**
- [ ] Figma: modal copy, layout, single dismiss CTA
- [ ] Ship #2738 excluded chipset list to client as detection table
- [ ] `is_below_minspec_android()` in the Android plugin — chipset/GPU read at launch (iOS analog: `is_low_spec_iphone()`, #1825)
- [ ] Modal shows once per app version; dismissal persisted
- [ ] Deep link + CLI flag to force the modal for QA, mirroring `low_spec_warning=true` / `--low-spec-warning` (#1825)
- [ ] Suppress in-app rating prompt on detected devices
- [ ] `SCREEN_VIEW` event `BELOW_MINSPEC_MODAL_SHOW` + dismiss event
