[FEATURE]:Bottom toolbar layout is too compact, causing agent names to be truncated when oh-my-opencode is installed, even though there is still enough unused space available #17755

Describe the enhancement you want to request

The bottom toolbar seems to have enough horizontal space, but the current layout is too compact. When the oh-my-opencode plugin is installed, the selected agent name gets truncated and cannot be fully displayed, even though there is still visible empty space in the container.

This makes the UI feel unnecessarily constrained and hurts readability, especially for longer agent names. It would be great if the bottom bar could use the available space more flexibly, for example by improving item spacing, resizing behavior, or allowing the agent selector to take more width before truncating text.

Expected behavior:

The agent name should be shown more completely when there is enough unused space in the bottom area.
The layout should adapt better when additional plugins (such as oh-my-opencode) add more items to the toolbar.
Actual behavior:

The toolbar remains tightly packed.
The agent label is cut off too early, even though the bottom area still has plenty of space.
