fix: use server-assigned connection name instead of local name

The MCP server assigns connection names like "PBIDesktop-demo-57947"
but we were saving and reusing "localhost-57947", causing "connection
not found" errors on subsequent commands. Now _auto_reconnect extracts
the server-returned connectionName from the Connect response.
