Browse Source 
* Fix master leader election startup issue

Fixes #error-log-leader-not-selected-yet

* Fix master leader election startup issue

This change improves server address comparison using the 'Equals' method and handles recursion in topology leader lookup, resolving the 'leader not selected yet' error during master startup.

* Merge user improvements: use MaybeLeader for non-blocking checks

* not useful test

* Address code review: optimize Equals, fix deadlock in IsLeader, safe access in Leader
