Fusion - the Fusion 360 Bridge

Design surfaces survive a bridge respawn (test-project handle persisted); dashboard re-stages on design-shaped errors too.

fusion_state base64 downscales oversized captures instead of refusing - Dashboard surface cards were imageless on PIL-less bridges.

Ralph findings: badge diagnostics + CLI transport fallback; parallel status (36.7s->3.0s); skeleton LEDs; tooltips on every button; per-target auto-green; auto-green heals a stuck add-in.

Driving-badge diagnostics: fusion_state.drivingBadge now reports enabled + lastError, and the taskbar call distinguishes unavailable/timeout/error instead of failing silently; timeout raised 6s->15s.

Window sizing converges: retry until the window is confirmed large, because Fusion restores its own saved geometry late in startup and can override an early resize.

Fusion's window is auto-sized to ~92% of the work area after launch (background, no activation); sticky opt-out verb.
