TUI: prompt rows wrap mid-word in narrow terminals #53061

Description

In a narrow terminal (about 60 columns or less), the two rows under the session prompt wrap character by character. Every text in each row is allowed to shrink, so the agent name, the model, the directory and the shortcut hints all get squeezed at once and wrap mid-word (Buil / d) instead of one item giving way.

#44551 shows the same wrapping in its captures; that issue was closed because its blank-row symptom came from the terminal app, but the wrapping itself reproduces in a normal terminal.

Plugins

None (--pure)

OpenCode version

1.18.34

Steps to reproduce

1. Open an existing session in a 40-column terminal: opencode --pure --continue
2. Look at the agent/model row and the directory row under the prompt.
