Adds the first-party Android OpenGL ES host under platforms/android with GLSurfaceView, JNI lifecycle handling, system-font matching, and three ABI builds. Fixes missing Android glyph output caused by GLES texture swizzles and removes round-cap/dashed-stroke AA seams. Includes updated Android integration and cross-platform documentation. Release packages are provided for Windows x64, Linux x64, and macOS universal; the Android host remains a source integration sample rather than a signed distributable APK.
