Composer placeholder "Type / for commands" no longer shows (desktop app)

What happens
The chat input box in the Claude Code desktop app is completely blank when empty. It used to show the grey hint text "Type / for commands".

What I expect
The placeholder hint to show when the input box is empty, as it did before.

Why it matters
Without the hint I cannot tell the input box is ready, and there is no reminder that "/" opens the command list. Typing "/" still works - only the hint is gone.

Steps to reproduce

1. Open the Claude Code desktop app.
2. Look at the chat input box with nothing typed in it.
3. The box is empty - no placeholder text.
