Summary

Track the release branch promotion for the MeteorTest Tencent deployment baseline.

Expected Behavior

The release branch should contain the deployment workflow, release policy docs, and Tencent production deployment baseline.

Proposed Changes

• Promote main release deployment track into release.
• Verify release CI and Tencent deployment.

Test Plan

• Release CI passed.
• Deploy Tencent on release passed.
• meteortest.jcmeteor.com returned the expected login redirect.

Completed by PR #108.
