Cmux Socket Policy

If you're working on cmux socket or CLI commands, this enforces two critical rules: don't block the main thread with telemetry spam, and don't steal focus from the user. It's specific about which commands get main-thread access (AppKit/Ghostty UI manipulation) versus what should run off-main (telemetry parsing, deduplication). The focus policy is strict: only explicit focus-intent commands like window.focus or workspace.select can touch focus state. Everything else must preserve user context. It's opinionated architecture guidance that prevents the two most common ways socket commands turn into laggy, disruptive experiences.
