grep_files

Finds files whose contents match a regular expression pattern, similar to Codex's grep_files tool.

• pattern: Required regular expression pattern to search for.
• include: Optional glob that limits which files are searched (for example *.rs or *.{ts,tsx}).
• path: Optional directory or file path to search (defaults to the current working directory).
• limit: Accepted for compatibility but currently ignored; output may be truncated for very large result sets.
