feat(ci): pre-built Android builder image + sccache

Replaces the 5 per-run tool-install steps (~2m 30s) with a pre-built container image (git.aleshym.co/funman300/android-builder) that ships Ubuntu 22.04 + Java 17 + Android SDK/NDK + Rust stable + aarch64 target + cargo-ndk + sccache. android-release.yml now runs inside the container and adds two cache steps instead: Cargo registry and sccache directory. sccache (RUSTC_WRAPPER) caches at the translation-unit level so partial hits survive Cargo.lock changes — far more resilient than caching the full target/ directory.
