ci.yml

name: CI

# Minimal compile gate for PRs and main. Until this existed, the release
# workflow was the repo's only build check, so uncompilable merges could land
# on main unnoticed — v1.6.8 alone shipped three separate "repair main" fixes.
#
# Deliberately just `cargo check`: fast enough to gate every PR, and it
# compiles the lib, bins, tests, and benches without running anything.
