[BUG] Search tool often does not work

Environment

• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [ ] Other: <!-- specify -->

Bug Description

Search tool often does not work. It's not that it never works, sometimes it does, which confuses the issue.

Steps to Reproduce

I can't give you specific steps but I can give you an example of conversation:

● Search(pattern: "utmdata\.js")
  ⎿  Found 0 files

● Search(pattern: "attachToForm")
  ⎿  Found 0 files
  ⎿  Interrupted by user

> use rg instead of your broken search tool

● Bash(rg -l "attachToForm")
  ⎿  AFFILIATE_SYSTEM_IMPLEMENTATION.md
     session/views/signup.view.php
     libs/js/utmdata/utmdata.js

Expected Behavior

I would have expected Search tool to find both of the phrases as easily as rg did.

Actual Behavior

Search tool found nothing and I had to tell Claude Code to use rg instead. This is a very common pattern for me.

Additional Context

This keeps happening for a while. I'm unable to tell you which update caused this, but it has been weeks and I have been waiting patiently for some update to fix it.
