A mid_conv_tool_change capability flag joins the model flag lists, gating whether tools can change mid-conversation.

A new model-capability flag, mid_conv_tool_change, joins existing flags like mid_conv_system and adaptive_thinking in the model-context flag lists used for deciding model behavior. It appears to gate whether tool definitions can change mid-conversation for a given model.
