📝 WalkthroughWalkthroughBootstrap now identifies post-snapshot table additions through resolved DDL history. It restores their spans and operators with table-specific timestamps, avoids adopting dropped tables, and validates failover, splitting, and replication behavior. ChangesDDL-backed bootstrap recovery

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Preserve the selected light-CI group tests.
This assignment ignores groups[10#${group_num}]. Every valid group now runs only maintainer_failover_when_operator. The light CI job skips all other tests in mysql_groups, kafka_groups, pulsar_groups, and storage_groups.
Add this regression test to the required group, or append it to the selected group. Do not replace the group list.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

What problem does this PR solve?
Issue Number: close #6202 ref #5083
What is changed and how it works?
Recover tables created after the bootstrap checkpoint from DDL history, preserving surviving dispatchers and split eligibility while repairing missing span coverage. This avoids duplicate scheduling during maintainer failover.
