fix: complete the MCP Apps handshake the way hosts validate it

The panel sent clientInfo and capabilities in ui/initialize, where the MCP
Apps schema requires appInfo, so hosts such as Claude rejected the handshake
and never showed the panel. It now sends exactly appCapabilities, appInfo and
protocolVersion, sends initialized without parameters, says so when a host
rejects it, and offers the link when God's Eye View does not load within 20
seconds. Checked against the MCP Apps SDK's own host bridge.
