Walkthrough

The release-8.1 initializer now skips dm_worker.rules.yml when copying bundled rules and restoring persisted rules for TiDB.

Changes: TiDB rule filtering

Layer / File(s)	Summary
Exclude the DM-only rule during initialization monitor-snapshot/release-8.1/operator/init.sh	The initializer defines DM_ONLY_RULES, adds an optional filename exclusion to restore_rules, and skips matching rules during restoration. It also skips that filename when copying bundled rules and passes it to the restore call.
