fix: add --no-messages flag to ripgrep to suppress file access errors

[roomote]

Fixes #6756

Summary

This PR adds the --no-messages flag to the ripgrep command arguments to suppress file access error messages (e.g., permission denied errors) that were causing the search_files tool to return empty results.

Problem

When ripgrep encounters files it cannot access due to permission issues, it outputs error messages that interfere with the JSON parsing of search results, causing the entire search operation to fail and return no results.

Solution

Added the --no-messages flag to the ripgrep arguments. According to the ripgrep documentation, this flag:

• Suppresses all error messages related to opening and reading files
• Still shows error messages related to pattern syntax errors
• Allows the search to continue and return valid results from accessible files

Changes

• Modified src/services/ripgrep/index.ts line 153 to include --no-messages in the ripgrep arguments array

Testing

• Ran existing tests for the ripgrep service - all tests pass
• The change is minimal and only affects error message suppression, not the core search functionality

---

Important

Adds --no-messages flag to ripgrep command in index.ts to suppress file access error messages, allowing search to continue with accessible files.

• Behavior:
  • Adds --no-messages flag to ripgrep command in regexSearchFiles() in index.ts to suppress file access error messages.
  • Suppresses errors like permission denied, but still shows pattern syntax errors.
  • Allows search to continue and return results from accessible files.
• Testing:
  • Ran existing tests for ripgrep service; all tests pass.

Reviewing my own code is like debugging in a mirror - everything looks backwards but the bugs are still mine.
