What's Wrong?

@anthropic-ai/claude-code@2.1.269, installed via npm on Windows, ships a win32-x64 native binary
whose embedded launcher does not run. Executing claude prints Bun's CLI help, and claude --version
reports the Bun runtime version instead of the Claude Code version. The PE metadata still claims
Claude Code. Version 2.1.268 (previous) and 2.1.270 (next) are both unaffected on the same machine.

What Should Happen?

claude should be opened without error
