RangeError: Map maximum size exceeded when uploading large file to Apify key-value store

# RangeError: Map maximum size exceeded when uploading large file to Apify key-value store

## What is going on

Uploading a zip file larger than about 9 MB to an Apify Actor's key-value store with `Actor.setValue()` (crawlee 3.1.3 / apify 3.1.1) throws `RangeError: Map maximum size exceeded`. Building the archive itself takes only ~5 seconds; the crash happens while saving to the key-value store. Smaller files save without any issue, so the failure is size-dependent.

## What actually works

Pass the data as a `ReadableStream` instead of a fully materialized Buffer/string. Convert the file into a ReadableStream and hand that to `Actor.setValue()`; the reporter confirmed this works for almost any file size. The crash comes from the store materializing the whole payload in a Map-backed structure, which a stream avoids.
