Cross-compile test binaries for Linux musl and build minibox-tester:latest in Colima. Parse {{arguments}} for: --target <triple> (default: aarch64-unknown-linux-musl).

1. Cross-compile with env vars CC_aarch64_unknown_linux_musl=aarch64-linux-musl-gcc and CARGO_TARGET_AARCH64_UNKNOWN_LINUX_MUSL_LINKER=aarch64-linux-musl-gcc:

   cargo build --target <target> -p miniboxd
   cargo build --target <target> -p minibox-cli
   cargo test --no-run --target <target> -p miniboxd --test cgroup_tests
   cargo test --no-run --target <target> -p miniboxd --test system_tests
   cargo test --no-run --target <target> -p miniboxd --test integration_tests
   cargo test --no-run --target <target> -p miniboxd --test sandbox_tests

2. Gather binaries from ~/.minibox/cache/target/<target>/debug/:

   • miniboxd, minibox (in bin dir)
   • Test binaries: find <name>-<hex> in deps/ by prefix, take newest

3. Assemble build context in mktemp -d:

   • Copy binaries to usr/local/bin/
   • Write run-tests.sh (runs each test suite with MINIBOX_TEST_BIN_DIR=/usr/local/bin)
   • Write Dockerfile: FROM alpine:3.21, COPY usr, COPY run-tests.sh, RUN chmod

4. Build in Colima:

   COPYFILE_DISABLE=1 tar --no-xattrs -c -C <ctx> . | colima ssh -- docker build -t minibox-tester:latest -

5. Clean up temp dir. Print: minibox-tester:latest ready in Colima

Run with: colima ssh -- docker run --rm --privileged minibox-tester:latest /run-tests.sh
