🚀 use prebuilt-only Rust tools to cut arm64 build time 🚀

- Switch cargo-binstall to --disable-strategies compile (no source fallback)
- Reorganize tools into core (reliable prebuilts) and secondary groups
- Add GHA cache for Docker buildx in Gitea workflow
- Disable binstall telemetry prompt for non-interactive builds
- Silently skip tools without prebuilts instead of hours-long compilation
