v0.4.2

Added

• Remote feedback delivery. brand_feedback now POSTs to brandcode.studio/api/feedback after local write. Fire-and-forget, never blocks the tool response. Agents in the field now send feedback directly to the Brandcode team.
• Local backlog drain. On every brand_feedback call, any previously unsent local feedback files are shipped to the remote endpoint and marked as sent. Existing local feedback from before this update will be drained on the next use.
• Remote send status. The response includes remote_sent: true/false so agents know if feedback reached the team. If remote fails, local file is the fallback.

This closes the visibility gap. We can now see feedback from external agents in Vercel Logs, not just from our own machine.
