ci: 移除 main 上的 release warmup

GitHub Actions cache 时效短且易被挤掉，push main 全量编三台
release 不划算。正式包只在打 v* tag 时编译。

 - Push the release commit to `main` by itself. Never push `main` and the version tag in one command or atomic push.
-- Wait for the `CI` workflow on the exact release commit to finish successfully before creating the tag. This allows the Linux, Windows, and macOS release-cache warmup to complete.
-- Never create the tag while required validation or the matching main CI run is failing, cancelled, missing, or still running.
+- Do not wait for main CI before tagging. Main CI does not compile release binaries; only the tag workflow does.
+- Never create the tag while local required validation is failing.
 - Never overwrite, move, or force-push `main` or a release tag.
 - Stop if `origin/main` moves away from the release commit before tagging. Reconcile the new remote state instead of tagging an older commit.
 - Use an annotated tag named `v<package-version>` and verify that the remote tag resolves to the release commit.
