Sync protocol: re-delete upstream-only workflows after merge

Adds step 3a immediately after the upstream merge in step 3. Without it,
every sync from anomalyco/opencode reintroduces the 30 workflows we
deleted in PR #14 (Discord, marketplace, SaaS deploy, moderation, etc.).

+### 3a. Re-delete upstream-only workflows
+
+Upstream ships 32 workflows we deleted in PR #14 (Discord webhooks, marketplace publishing, SaaS deploy, OPENCODE_API_KEY-gated automation, community moderation, Nix flake, upstream test surface). The merge will reintroduce them. Re-delete:
+
+```sh
+rm -f .github/workflows/{beta,close-issues,close-stale-prs,compliance-close,containers,daily-issues-recap,daily-pr-recap,deploy,docs-locale-sync,docs-update,duplicate-issues,generate,nix-eval,nix-hashes,notify-discord,opencode,pr-management,pr-standards,publish,publish-github-action,publish-vscode,release-github-action,review,stats,storybook,sync-zed-extension,test,triage,vouch-check-issue,vouch-check-pr,vouch-manage-by-issue}.yml
+```
+
+Keepers: `release.yml` (ours) and `typecheck.yml` (retargeted to `main`). If upstream adds a new workflow file we haven't classified yet, leave it on disk and flag it in the PR body for human review.
