[BUG] `claude agents` does not use `claude` binary in path, but rather tries to identify path

Preflight Checklist

What's Wrong?

When using claude agents session can not be spawend and are failing with

  '[worker crashed (ENOENT: no such file or directory, posix_spawn
  '/opt/homebrew/Cellar/<name of our private ClaudeCode cask>/2.1.140/libexec/claude') — respawning…]

Note that ClaudeCode tries to find the binary in the Cellar ( Formulas ) instead of Caskroom ( Casks )

What Should Happen?

claude agents should simply use claude from PATH or preferable use argv[0] to spawn subsessions.
