Allow escaping comma in cursor rules glob patterns

Cursor rules supports a comma separated list of glob patterns like this:

globs: example/**/*.txt,example-2/**/*.txt

Glob patterns typically support the following syntax:

{a,b,c} - Matches any of the coma-separated patterns

But you can’t use that with Cursor - it looks like it takes the globs: line and splits on ,, then treats each as a separate glob.

Please add support for escaping commas, or support putting each glob on a separate line.

It turns out cursor rules uses gitignore-style patterns, not unix-style globs. They’ve updated their documentation to clarify this.
