v3.2-Pre-Alpha

After a Windows installer is uploaded and its release is published, automatically announce it in Change Log Discussions with a direct EXE download link, a brief plain-text overview, published documentation links, and changed files with diff previews. Full diffs and patches link to immutable commit comparisons; the announcement includes no PR links.

Select the correct published documentation pages through Documentation: lines in the merged engine PR description. Require an explicit mapping or Documentation: none for changes without a docs update. Copy the engine PR's labels to the Discussion and synchronize them on reruns.

Retries update the existing announcement for the release. Failed uploads never announce; announcement or label failures leave the release available and can be repaired by rerunning publication. Add the required Discussions permission and document configuration, preview limits, and recovery.

Validation: all 21 release automation tests pass; actionlint v1.7.7 passes for all workflows; git diff --check passes. Read-only GitHub API checks confirm category discovery, Discussion label queries, and commit comparisons work. No live announcement was posted during testing.
