Malte UblandClaude Opus 5.5 4e0e7fc1af Box URL into checked-dynamic unions beside fetch handles ...

fetch's input under @types/node is string | URL | Request. A union with a
checked-dynamic arm collapses to the checked-dynamic representation only
when every sibling survives the collapse; URL did not qualify, so the type
(and anything typed as typeof globalThis.fetch, such as a custom fetch cast
through unknown) did not compile. URL's handle boxes by reference, keeps its
accessors and setters, answers instanceof URL and checks back out to the
typed value, so URL arms now join the collapse. A fetch() input typed
string | URL also converts through the checked-dynamic input path instead
of being narrowed to a string, which threw on the URL arm.
