Two small Phase 1 follow-ups for the Android target:
1. tauri.conf.json: add `bundle.android.minSdkVersion: 24`. Android 7.0
is the floor — gives us Vulkan availability (for the eventual GPU
feature flag), AAudio for cpal, and is what Pixel-class hardware
tests against. Keeps the global `identifier` on `uk.co.corbel.kon`
for now; the Corbie rebrand sweep will land `corbel.technology.corbie`
as a single coherent commit.
2. src/lib/utils/runtime.ts: add `isAndroid()` and `isMobile()` helpers
alongside the existing `hasTauriRuntime()`. Both use UA sniffing —
sufficient for feature-gating UI, never for security decisions.
These are how the Svelte side will hide:
- hotkey config (no global hotkey API on Android)
- paste-mode picker (auto-paste maps to a copy-only flow)
- meeting auto-capture toggle (process list unavailable)
- multi-window buttons (open-viewer, open-float, etc.)
- system-tray-related affordances
Tauri 2 doesn't expose a synchronous platform-detection helper that
works during initial render, so UA sniffing is the pragmatic choice.
