Linux build & smoke test fixes for the release workflow

Description

Linux build & smoke test fixes

Cross-compile (Dockerfiles)

• Bumped Dockerfile.cross-{gnu,gnu-aarch64,musl,musl-aarch64} from Ubuntu 20.04 (EOL repos) to 22.04.
• Added clang + libclang-dev so bindgen/zstd-sys find stddef.h.
• Builds now run fully inside the container, avoiding host GLIBC mismatches.

Smoke test (.github/workflows/release.yaml)

• Added plugin install source/mock and plugin install reaction/log steps (with --skip-verification) before the hello-world smoke test on Linux, Alpine/musl, and Windows, populating bin/plugins/.

Test config

• Updated tests/integration/hello-world/config.yaml to match the smoke runner (mock source + log reaction loaded from bin/plugins).

Plugin compatibility (Cargo.toml / Cargo.lock)

Bumped host deps to match the latest plugins on ghcr.io/drasi-project:

• drasi-host-sdk 0.6.0 → 0.6.2
• drasi-lib 0.6.0 → 0.6.1
• drasi-core 0.4.2 → 0.4.3

Without this bump the resolver rejected published plugins as incompatible.

Result

Linux GNU + musl cross builds succeed, and the post-build smoke test passes on Linux, macOS, and Windows.

Pull request overview

This PR updates the release workflow and cross-compilation environment to fix Linux (gnu + musl) builds and make the post-build “hello-world” smoke test succeed by ensuring required plugins are available and compatible.

Changes:

• Update cross-compilation Dockerfiles (notably moving to Ubuntu 22.04 and adjusting toolchain/build deps) to resolve GLIBC/bindgen-related build failures.
• Update the release workflow to install cross from git and pre-install required plugins before running the hello-world smoke test across platforms.
• Bump Drasi host/plugin dependencies to match published plugin compatibility and adjust the integration test config accordingly.
