Write-heavy Slang release engineering: update the SPIRV-Tools/SPIRV-Headers submodules and integrate GitHub master into the internal GitLab forks (the slang + slang-rhi + slangpy OptiX triad). Use when cutting a release, syncing SPIRV, or rebasing the GitLab nv-* branches. Invoke via /slang-release. This skill performs destructive git operations (force-pushes) and always confirms first. For read-only maintainer reporting (daily report, release notes drafting, issue prioritization), use slang-maintainer-tools instead.
