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.

node-types fixture

A project whose node_modules contains @types/node — the adoption path for real-world Node/TypeScript projects. The vendored node_modules are COMMITTED TEST DATA, pinned so the type surface (and therefore the pinned diagnostics) never drifts with the registry:

@types/node 24.13.3
undici-types 7.18.2 (its dependency — declares the web-platform globals: fetch/Response/AbortSignal/ReadableStream/...)

What the fixture pins (see tests/harness/project-config.test.ts):

argv-env.ts — the SUPPORTED process surface (argv, env) typed by @types/node lowers statically and the binary runs: with @types/node present, the shipped fallback declarations for process/node:fs/ console stand down (their types come from @types/node), but the same members lower to the same libCalls, recognized by name + @types/node provenance.
fenced.ts — surface @types/node DECLARES but scriptc does not lower (process.uptime, Buffer.from, setInterval) reports the SC2020-family fence naming @types/node, instead of typechecking its way into a broken binary — and never a raw "Cannot find name" error.
source-import/ — an imported TypeScript source may use the RequestInfo global supplied by TypeScript's default DOM lib while scriptc adopts the project's @types/node declarations.

Projects WITHOUT @types/node (every other fixture and the whole corpus) keep the shipped fallback declarations and behave exactly as before.
