Canvas Notebook 2026.7.2.2

Highlights

• Fix: 413 Request body too large — When the agent reads multiple images via the read tool, images are now compacted to WebP (max 2048px, quality 82) before being sent through the Control Plane chat proxy. Previously, large raw base64 payloads exceeded the Fastify body limit.
• Onboarding timezone save logging — Added detailed server- and client-side logging for the onboarding language/time zone save flow to help diagnose the "Sprache und Zeitzone konnten nicht gespeichert werden" error.
