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

Fixes #6756

When ripgrep encounters file access errors (e.g., permission denied), it would cause the search_files tool to return empty results. Adding the --no-messages flag suppresses these error messages while still showing pattern syntax errors, allowing the search to continue and return valid results from accessible files.
