Conversation
- Add Swatinem/rust-cache to every job that runs cargo build/test - Replace manual Go tarball download with actions/setup-go - Cache kraft-hyperlight binary (keyed on workflow file hash) - Replace cargo install --git with local cargo build on Windows (avoids re-cloning the repo; lets rust-cache take effect) Signed-off-by: danbugs <danilochiarlone@gmail.com>
