dash

1// dash: one dashboard for the Revenantworks skills (owner 2026-10-08). A collector counts what
2// happens (skill fires, failures, likely misroutes, tokens, meters, command and permission-prompt
3// shapes), never text; renderers show it on the status line, in the /dash pane (text where no pane
4// draws), in VS Code from feed.json, and as a mobile snapshot. A suggestion queue proposes, never
5// builds. Every `$` use lives in this file; pure logic sits in *-logic.ts and lib/.
6// Hook work is kept cheap: hooks push counts to memory; a timer writes them.
