The workflows in this directory are split so that pull requests get fast, review-friendly signal while main still gets the full cross-platform verification pass.

• rust-ci.yml keeps the Cargo-native PR checks intentionally small:
  • cargo fmt --check
  • cargo shear

• rust-ci-full.yml is the full Cargo-native verification workflow. It keeps the heavier checks off the PR path while still validating them after merge:
  • the full Cargo clippy matrix
  • the full Cargo nextest matrix
  • release-profile Cargo builds
  • Linux remote-env tests

• Keep rust-ci.yml fast enough that it usually does not dominate PR latency.
• Reserve rust-ci-full.yml for heavyweight Cargo-native coverage.
