2ro d95efef896 linux: build_release.sh produces a correct arm AppImage (per-arch runtime)
The arm path hardcoded ARCH=x86_64 and the x86_64 type2 runtime, so a
`build_release.sh arm` run produced a broken AppImage (x86_64 runtime wrapping
an aarch64 binary). Derive ARCH and the runtime file from the target arch, and
have toolchain.sh fetch runtime-aarch64 alongside runtime-x86_64. This restores
GRIM's linux-arm AppImage release type; verified the output is an ARM aarch64
AppImage.

# Fetch the canonical GRIM build toolchains (code.gri.mw/DEV) into .toolchains/.
#
# These mirror exactly what upstream GRIM's CI uses, so Goblin cross-builds every
# platform from one Linux box the same way GRIM does — instead of relying on
# whatever NDK/zig/appimagetool happens to be installed on the machine.
#
# Idempotent: each tool is skipped if already present. Linux x86_64 host only
# (the box we build releases on). Writes .toolchains/env.sh with the exports the
# build scripts source; run nothing else by hand.
#
# Usage:
# scripts/toolchain.sh # core: ndk zig appimage (what desktop+android need)
# scripts/toolchain.sh sdk gradle # add the Android SDK + Gradle
# scripts/toolchain.sh osxcross # build the macOS cross-toolchain (heavy)
# scripts/toolchain.sh all # everything
#
