agra 561ad03a7c android: Platform-owned entry bridge + .android OS enum variant
User writes BOTH `main` and a 3-line `android_main(app)` trampoline.
The library provides `sx_android_bootstrap(app)` (stashes the NDK app
pointer into a platform-owned global) and `AndroidPlatform` impl of
the Platform protocol. The library NEVER references `main` — the OS-
shape entry symbol lives in user code where the other entry symbols
already live. iOS / SDL3 keep their existing shape; only Android adds
the trampoline.

Cross-cutting bits this commit ships:

  library/modules/compiler.sx
    Add `android` variant to `OperatingSystem`.

  src/ir/lower.zig
    - injectComptimeConstants: map TargetConfig.isAndroid() → .android.
    - New Pass 4 `checkRequiredEntryPoints`: emit a clean diagnostic
      when `--target android` is requested but `android_main` isn't
      defined, instead of letting the user crash on a dlopen-time
      missing-symbol error.

  library/modules/platform/android.sx
    AndroidPlatform impl of the Platform protocol — EGL bringup on
    `APP_CMD_INIT_WINDOW`, ALooper(0) polling, dispatches the user's
    frame closure each ~16 ms tick. `sx_android_bootstrap(app)` is the
    only function exposed for the entry trampoline.

  examples/99-android-egl-clear.sx
    Rewritten to use the new pattern: minimum `main` + `android_main`
    pair, AndroidPlatform-driven render loop. Doubles as the usage
    reference users hand off to the compiler diagnostic.

Verified on Pixel 7 Pro: purple clear-color frame, periodic
`rendered 60 frames` logcat lines. iOS-sim chess + 86/86 regression
tests pass.
