Post selected standup presenter to team channel

When your daily standup lacks a named presenter, team prep stalls and meetings start late. Meetings kick off on time after a clear presenter announcement and attendance mark, same day.

Overview

Standups lose momentum when nobody knows who will present; that wastes time and dilutes accountability. This flow guarantees a presenter is chosen, announced, and recorded ahead of each meeting so standups start on time and prep visibility appears within minutes.
