/reload-plugins reported '0 plugin MCP servers'. Root cause: plugin.json had
"mcpServers": "./.mcp.json" — a string path, which is neither a valid inline
object nor a recognized reference (per docs, plugin MCP servers are a root
.mcp.json OR an inline object in plugin.json), so it parsed to zero servers.
Inline the mcpServers object directly in plugin.json and remove the separate
.mcp.json. The user_config substitution syntax was already correct
(plugins-reference: values substitute as ${user_config.KEY} in MCP configs).
