Reflect v100.2.0 (auto-update via the GitHub Pages feed), the Homebrew cask bump, and the will-release gating that lets non-release pushes build and test without cutting a release.
Reset .fork-sync-state to v11.3.0 (last-synced upstream tag) and remove the release-tail step that overwrote it with the fork release tag, which would stall upstream-sync. Update SESSION-STATE/TODO/CICD-STATUS/README for the live signed+notarized v100.1.0 release.
