ci: update release asset targets

[CaseyLabs]

Changes

• Add Windows ARM64 and Linux ARM64 binaries to the GitHub Actions build/release workflows.
• Replace the Linux ARM5 builds with Linux ARMv7 (a more realistic end-user use-case).
• Keep the latest and numbered release workflows aligned on the same build, checksum, and upload asset names.
• Extend the shared codegen-and-test action to cross-compile release targets during PR validation.
• Emit grouped, verbose build logs for each release target so CI failures identify the target that failed.

Validation

• git diff --check
• actionlint .github/workflows/build-and-release.yml .github/workflows/release-latest-assets.yml
• Parsed .github/actions/codegen-and-test/action.yml as YAML with Ruby.
