v0.15.2-fork.5

Features

• Responsive footer groups session identity, location, context and rate windows without repeating default states.
• A bounded agent shelf shows each running agent's model, current activity, usage and elapsed time.
• Ctrl+T groups plan steps, agents and other tasks; Enter opens the selected agent's inspector with model choice, recent tools, prompt and saved messages.

Fixes

• Preserve resolved child models and usage across out-of-order background inventory and completion events.
• Feed status-line commands the resolved human model name instead of a catalog option label.
• Keep agent selection and message content associated while live inventory changes.
