Runs StarForth session (52 theories) in parallel with the board build matrix. Caches the Isabelle2024 installation (~800MB) and the compiled heaps keyed on proof/**/*.thy + ROOT, so only theory changes trigger a full rebuild. Uploads the build log as an artifact on every run (pass or fail) for audit. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
