Glob patterns with brace expansion ({a,b,c}) now have a budget guard. If expanding a brace pattern would produce too many results or exceed the byte budget, it is used unexpanded with a warning:
> Brace pattern expansion exceeds the budget; using it unexpanded: {pattern}
This prevents accidental combinatorial explosion from deeply nested or wide brace patterns.

Budget guard (search for "Brace pattern expansion exceeds the budget")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
