# CI gate for skillpack (design §7.4): fmt + clippy + full test suite on every
# PR; no PR merges without green CI.
#
# Matrix: ubuntu, macos, windows — verifies cross-OS compile + PATHEXT
# resolution on Windows (cmd.exe appends PATHEXT; Rust's Command does not;
# which_on_path probes name{ext} manually). Runtime prereqs (node, python,
# go, ruby) installed via the official setup-* actions so each OS gets a
# working runtime without hand-rolled apt/choco/brew logic.
#
# `--include-ignored` runs the Go + Ruby `#[ignore]`-gated round trips
# because the runners ship those runtimes (the dev machine does not). Each
# ignored test self-skips via a runtime probe, so a missing runtime
# anywhere degrades the same way it does locally rather than failing.
