Run implementation checks on the ccswarm workspace:
# 1. Format check
cargo fmt --all --check
# 2. Lint check
cargo clippy --workspace -- -D warnings
# 3. Tests
cargo test --workspace
# 4. Build verification
cargo build --workspace
Note: ccswarm uses Rust 2024 Edition. std::env::set_var requires unsafe, pattern matching has implicit borrowing.
Report results as JSON: { format, clippy: { warnings, errors }, test: { passed, failed, ignored }, build, overall }.
