Slash command picker does not filter — always executes first item

Summary

Typing / shows the slash command picker, but typing further does not filter the list. The first command in the list is always executed regardless of what is typed.

Environment

• Claude Code version: 2.1.45
• OS: macOS (Darwin 25.2.0)
• Terminals tested: Ghostty 1.2.3 and Terminal.app (both affected)

Steps to Reproduce

1. Type / in the Claude Code input
2. Slash command picker appears with a list of available commands
3. Type a command name (e.g., clear)
4. Press Enter
5. Expected: /clear executes
6. Actual: The first item in the picker list (e.g., /commit) executes instead of the typed command

Additional Context

• The filtering was working earlier in the same session, then stopped working
• Restarting Claude Code did not resolve the issue
• The issue is not terminal-specific (reproduced in both Ghostty and macOS Terminal.app)
• Similar issues were fixed in v2.1.14 and v2.1.20, so this may be a regression
