Closes#37369
---
The `glob_search` tool in `FilesystemFileSearchMiddleware` documents
that
results are "sorted by modification time (most recently modified
first)",
but the implementation was returning files in the arbitrary order
provided
by `Path.glob()`.
This change adds a sort by modification timestamp (`modified_at`), in
descending order, immediately before extracting the file paths for the
return value. No public API changes.
