Buffer attach events until winit state exists, keep spawned daemon ownership
until the reaper handoff, and detach daemon stderr from the launcher terminal.
Tighten direct GPU CLI guidance and sibling discovery. Strengthen managed
connector unit and process acceptance coverage for transient retries, timeout
reporting, hermetic paths, and deterministic loser reaping.
Add the root --gpu broker, strict GPU entry points, daemon connect-or-start orchestration, process-group isolation, bounded retry, named child reaping, and a deterministic headless lifecycle probe. Cover the complete launch matrix with real subprocess acceptance, make root Cargo runs unambiguous, and document the coherent build and one-command workflow.
