Browser upload link for network-restricted AI clients

A new get_upload_link MCP tool generates a Vello web URL your AI assistant can hand you when it cannot upload files directly — for example, in sandboxed or corporate-proxy environments that block *.supabase.co. You open the link in your browser, drop the file onto the focused upload page, and it is automatically attached to the target thought or insight. No configuration changes required on your end.
