/**
 * pi-cmux: Native cmux extension for pi.
 *
 * Phase 1: Context-aware notifications via the cmux socket API.
 * Phase 2: Sidebar status pills (model, state, thinking, tokens).
 * Phase 3: Custom tools for the LLM (browser, workspace, notify).
 *
 * Gracefully degrades: if not running inside cmux, the extension
 * is a silent no-op.
