Malte UblandClaude Opus 5.5 8a02efaa91 Type process.getBuiltinModule results as module namespaces ...

Under @types/node, process.getBuiltinModule("node:os") types as the
module namespace, which lowered as an unchecked dynamic value and failed.
A string-literal id naming a supported builtin now lowers to the namespace
value an `import * as` binding has, including pi's cast-and-probe spelling
`(process as P).getBuiltinModule?.("node:os") ?? null`; a nullable
namespace binding narrowed present keys the same member tables, and a
namespace is truthy. process.features read as a whole value (`"sea" in
process.features`) is an object holding none of the flags, matching the
existing member reads.
