What's Wrong?

Ripgrep search failed A system error occurred
(spawn C:\home\runner\work\claude-cli-internal\claude-cli-internal\vendor\ripgrep\x64-win32\rg.exe ENOENT)

What Should Happen?

Expected: Extension uses its bundled rg.exe relative to install path
Actual: Path is hardcoded to CI build machine path which doesn't exist on end-user machines
