Clearing input with cmd+backspace breaks w/ `messages_half_page_up` configured

[jesseleite]

Description

This is a weird one!

It seems clearing the input with cmd+backspace (a common MacOS-ism) breaks when this messages_half_page_up keybind is configured:

But if I delete that one line and relaunch opencode, cmd+backspace works just fine 🤔

OpenCode version

1.0.223

Steps to reproduce

1. Configure the following keybinds in opencode:

"keybinds": {
  "messages_half_page_up": "ctrl+u",
  "messages_half_page_down": "ctrl+d"
}

2. Try to cmd+backspace to clear the prompt input in opencode on MacOS.

This issue might be a duplicate of or related to existing issues. Please check:

• cmd + backspace doesn't work #1471: cmd + backspace doesn't work (similar MacOS issue with cmd+backspace)
• Command backspace not working from 1.0 #3783: Command backspace not working from 1.0 (another MacOS cmd+backspace issue)
• When input is nonempty, ctrl+d does app_exit instead of input_delete #5457: When input is nonempty, ctrl+d does app_exit instead of input_delete (keybind conflict issue)
• Ctrl-u not clearing input field #3647: Ctrl-u not clearing input field (keybind conflict with input clearing)

The root cause appears to be related to keybind configuration conflicts. All of these involve input clearing/deletion keybinds not working as expected.
