feat: brace expansion

[wolfv]

I am looking into two issues:

{1..5} should expand to 1 2 3 4 5, also in word parts. This already works for globs in deno-task-shell, so it's an extension. Should follow the rules of bash (first brace extension, then globs, for example).

"linux-64" == linux* should use pattern matching (and not glob expansion). If a glob is detected on the right hand side of a binary operation like this, then it's used as a pattern to evaluate against the string on the left hand side. We can just use the glob that is already in use for this, but we need to prevent the current expansion and return a pattern.
