Glob or regex patterns for recursively adding folders and files to prompt context

[nickchomey]

Currently, when adding a folder to Roo’s context (e.g., using @folder/path), the inclusion is non-recursive - only the top-level files are considered. It would be very useful to have the option to include folders recursively, so that entire repositories or nested subdirectories can be added in a single step.

One possible approach would be to support glob or regex patterns, such as allowing @folder/path/**, or even @folder/path/**/*.js to recursively include all desired files within the specified path and its subdirectories.

I see that with the new ripgrep mechanism used for the context search (implemented in #1824), it obviously just returns No results found if you add a wildcard to the string. So, something within that would need to be modified to accept wildcards/globs/regex patterns.

This would allow us to more easily add the appropriate context to our prompts
