Detailed Description

Cross-platform thread helpers and registry used by OP_THREAD_SPAWN/OP_THREAD_JOIN.

This file provides a tiny cross-platform threading layer (Windows/UNIX) embedded into the VM translation unit. It exposes utilities used by VM opcodes to spawn a function call in a background thread and later join it to retrieve the result.

Notes:

• Thread registry is bounded by FUN_MAX_THREADS; not intended for high concurrency.
• Each task owns its argument Values and transfers ownership of the result to the caller on successful join.
