[BUG] keybindings.json presence causes input to not clear after submit; keybinding actions ignored

What's Wrong?

When a ~/.claude/keybindings.json file is present, two bugs occur:

1. The input field is not cleared after submitting a message — the text remains visible and accumulates into subsequent messages
2. Custom keybinding actions (e.g. chat:newline, chat:submit) are ignored entirely; Enter always submits regardless of configuration

What Should Happen?

• Input should clear after submission
• enter: "chat:newline" should insert a newline instead of submitting
• cmd+enter: "chat:submit" should submit the message

Error Messages/Logs

Steps to Reproduce

1. Create ~/.claude/keybindings.json with this content:

```json
{
"$schema": "https://www.schemastore.org/claude-code-keybindings.json",
"bindings": [
{
"context": "Chat",
"bindings": {
"enter": "chat:newline",
"cmd+enter": "chat:submit",
"meta+enter": "chat:submit"
}
}
]
}

  2. Start Claude Code
  3. Type a message and press Enter — it submits (should add newline)
  4. Type another message and submit — the previous message text is still present in the input

  - Tested with a clean environment (env -i) — same result
  - The bug is triggered by the mere presence of the file, regardless of content
