• Rust 1.70+ (e.g. via rustup)
• Linux (primary target; some modules depend on /proc, /sys)

cargo build
cargo run -- cpu
cargo run -- all --json

Release build with optimizations:

cargo build --release

cargo test
cargo test --all-features

cargo fmt --all
cargo clippy --all-features -- -D warnings

1. Create src/modules/<name>.rs with a struct implementing DiagnosticModule.
2. In run(), gather data, build DiagnosticReport with findings/metrics/recommendations.
3. In src/modules/mod.rs, add the module to get_module and all_modules.
4. In src/cli/args.rs, add a Commands variant and options.
5. In src/main.rs, map the subcommand to module name and ModuleConfig in command_to_module_config, and ensure run_all_and_output includes it when using all.
