[BUG] Glob tool fails silently when pattern contains relative directory path without path parameter

What's Wrong?

Glob tool returns "No files found" when the pattern includes a relative directory path (e.g., subdir/**/*.md) without specifying the path parameter, even though files exist.

The workaround is to use the path parameter separately:

• ❌ pattern: "subdir/**/*.md" → No files found
• ✅ pattern: "**/*.md", path: "subdir" → Files found

What Should Happen?

Either:

1. Relative directory paths in the pattern should work, OR
2. The tool should return an error/warning explaining the limitation

Silent failure causes agents to make incorrect decisions.

Error Messages/Logs

No files found

No error, no warning. Just empty results.

Steps to Reproduce

1. Have files at <project>/subdir/file.md
2. Working directory is <project>
3. Run: Glob(pattern: "subdir/**/*.md") → Returns "No files found"
4. Run: Glob(pattern: "**/*.md", path: "subdir") → Successfully finds files
