[BUG] Pressing Tab key in Desktop app crashes the app

Bug description
Pressing the Tab key in Claude Code Desktop app causes the app to crash.
It seems Tab triggers autocomplete and floods the input with a large amount of data,
causing macOS to force-quit the app.

Steps to reproduce

1. Open Claude Code Desktop app
2. Open a session
3. Press the Tab key

Expected behavior
Tab key should work normally (or do nothing).

Actual behavior
App crashes immediately after pressing Tab.

Environment

• Claude Desktop version: 1.8089.1
• macOS: darwin 24.5.0
• Machine: Mac (Apple Silicon)
