Malte UblandClaude Opus 5.5 7be1a990c7 Write run-time-typed chunks to the process streams (W2) ...

`process.stdout.write(data)`/`process.stderr.write(data)` with a chunk
whose type is only known at run time (`any`, or a `string | Uint8Array`
union) was refused. Lower the one-argument form to the new
`process.stdioWriteDyn` libCall, and factor the existing stdio write
method's dispatch into `scr_stdio_write_call` so both share Node's
Writable validation: a string or a Uint8Array/Buffer writes its bytes,
null throws ERR_STREAM_NULL_VALUES, and any other value throws
ERR_INVALID_ARG_TYPE, all before anything is written.

`scr_stdio_write_call` keeps its exact statements, so it is only the
call sites that change; programs that contain a JS stdio value and link
the events unit may differ (their write method's bytes).

Corpus: `tests/corpus/process-write-dynamic-chunks.ts` covers strings,
Buffer, Uint8Array, a string | Uint8Array union, a JSON field, and the
four invalid chunks with their codes and messages.
