Add xgenext2fs installation support to setup-action - #5
Merged
Conversation
Adds an `xgenext2fs-version` input (default `latest`, `none` to skip) and a matching output. On Linux the `xgenext2fs_<arch>.deb` asset of a cartesi/genext2fs release is downloaded, verified against the digest published by the releases API, and installed with `apt-get` so its `libarchive13` dependency is resolved; on macOS the `cartesi/tap/xgenext2fs` formula is used. Every genext2fs release is published as a GitHub pre-release, which `/releases/latest` ignores, so `latest` resolves through the release list instead. The Homebrew helpers (quiet CI environment, per-formula trust, `brew --prefix`) and the `apt-get` invocation move out of machine.ts into shared modules, with `apt-get update` now running once per job rather than once per package.

The genext2fs releases are no longer published as pre-releases, so `/releases/latest` resolves them and the release-list walk added to work around that is no longer needed. `xgenext2fs-version: latest` now goes through the same client method as the emulator.
