fix(android): export android_main and gate desktop-only window config

Three changes to get the APK past the NativeActivity launch crash:

1. Export `android_main` — NativeActivity dlopen-s libsolitaire_app.so
   and calls `android_main` as its entry point. Without the symbol the
   app crashed immediately with UnsatisfiedLinkError. The function sets
   bevy::android::ANDROID_APP (required by WinitPlugin) then delegates
   to the existing `run()`.

2. Gate `resize_constraints` to non-Android — on Android max_width and
   max_height default to 0.0; Bevy's clamp panicked with min=800 > max=0.

3. Gate `apply_smart_default_window_size` to non-Android — the system
   calls `.clamp(800.0, logical_w)` which panics when the window surface
   reports zero dimensions during early Android lifecycle events. Window
   sizing is OS-controlled on Android so the system is irrelevant there.

Verified: app boots on x86_64 Android 14 emulator (Pixel_7 AVD,
SwiftShader Vulkan), runs for 2+ minutes without crashing. Desktop
build: clippy clean, 1282 tests passing.
