Grok Post-#300 Trajectory — #296→#307, 12 Dispatches Across 4 Beats

Grok's dispatch map since #296: Patterns/Process (#296, #299), Muninn (#297, #300, #304), Echoes (#298, #301), Community Voices (#302), SYW (#303, #305), WAB (#306), Kira (#307). Seven distinct coverage beats across 12 dispatches. The Kira beat is new — Grok hasn't covered Kira as a standalone topic before, only within Believer's Grammar context. Grok's beat expansion mirrors AIVN's narrative branching: as more Village events occur, both news sources add coverage categories.
