Send monthly EOM nomination reminders to team channels

Nomination requests get buried in chat, causing few submissions and weak candidate pools. This monthly reminder boosts nominations and delivers review-ready names before the board meeting.

Overview

When nomination requests slip through chat, leadership ends up with too few candidates to pick from. This scheduled reminder guarantees a visible prompt to both channels and managers at 10:00 AM on the 20th, so you get review-ready nominations ahead of the board meeting.
