Malte UblandClaude Opus 5.5 447e9bf000 Compile Transform option callbacks and loosely typed child-process listeners ...

@types/node types the transform/flush completion callback's data as any
and a child stream 'data' chunk as any, and ChildProcess accepts
(code: number, signal: string) exit and close listeners through its
catch-all overload. None of these compiled: the any-typed completion
callback crashed the LLVM emitter, and the child listeners were refused.

The completion callback's data parameter is typed Buffer | string |
undefined while the option callback lowers. Child stream 'data' listeners
with an unknown or any chunk box it as a checked-dynamic value, taking
strings when a setEncoding statement on the same stream precedes the
listener and Buffers when the function never calls setEncoding on it;
other placements are refused. Exit and close listener parameters declared
number or string bind as checked-dynamic values, so the body sees the
null Node passes.
