Generate a new fingerprint for a platform

get

Picks a random library fingerprint matching platform, then uniquifies it: a fresh Sec-CH-UA platform_version, host-aware hardware_concurrency/device_memory (never claims more than the real machine), and a screen clamped to the real display. Returned unsaved — feed it to a create endpoint as fingerprint.
