Subject: [PATCH] ci: add linux-arm64 binary to release and CI (#484)

Add aarch64-unknown-linux-gnu build using native ubuntu-24.04-arm
GitHub-hosted runner, avoiding cross-compilation entirely.

- release.yml: add hindsight-linux-arm64 matrix entry
- test.yml: add build-rust-cli-arm64 job to verify compilation on PRs

Closes #483
