Summary:
`globset` supports multiple matching strategies, including literal prefix
(backed by AhoCorasick), or regexp, etc.
In theory patterns like `foo/**` (where `*` cannot match `/`) can use `foo`
prefix strategy. However, the implementation detail of `globset` wouldn't
accept it as a prefix. But `foo/*` (where `*` can match `/`) can be treated as
a prefix. Transform the former pattern to the latter to hint `globset` to use
the optimal strategies.

Summary:
simpkins encountered a case where the treematcher does not work with many
patterns. It turns out `globset` has a hard-coded regex size limit (10MB).
Implement proper error handling so we can detect such issues and fallback to
slower paths.
