hermes - 💡(How to fix) Fix [Bug]: TUI content width does not follow terminal resize — large empty space on right side [1 pull requests]

Bug Description

When the terminal window is resized horizontally to be wider, the content area of hermes --tui does not expand to fill the available width. Instead, the content stays at a fixed width, leaving a large empty space on the right side of the terminal.

To Reproduce

1. Run hermes --tui
2. Resize the terminal window wider — drag from 80 columns to 160 columns
3. Observe: the content width stays fixed at approximately 80-100 columns
4. The right side of the terminal window becomes empty/unused space

Expected Behavior

Content should adapt to the full terminal width, expanding to fill the available columns.

Actual Behavior

• Content width is capped at a fixed maximum, regardless of terminal width
• Right side of the terminal window is empty
• Beyond a certain window width, content stops expanding entirely
• No horizontal scrollbar appears (content is not wide enough to scroll — the TUI simply doesn't use the full width)

Screenshot

Window is wide, but content only fills ~2/3 of the width, right side is empty:

Environment

• Hermes Agent: latest main (4ccd141b)
• macOS: 26.5
• Terminal: Terminal.app

Additional Context

• This is unrelated to the voice-input rendering collapse bug
• Likely caused by a hardcoded maxWidth in the Ink layout components
• The composer.cols value appears to not be the limiting factor — it may be a max-width set on the top-level <Box> or container in appLayout.tsx or the transcript pane
