Better generic tool result support

[cboos]

I found out that we don't show the tool result side, for a tool without specalized support:

Both the content and the toolUserResult could be used to present something more interesting:

{"content":[{"type":"tool_reference","tool_name":"mcp__plugin_clmail_clmail__terminal"}]}

{"toolUseResult":{"matches":["mcp__plugin_clmail_clmail__terminal"],"query":"select:mcp__plugin_clmail_clmail__terminal","total_deferred_tools":35}}

(content seems more to the point)
