Vitalii 07c382914c scripts/wasm, worker: fixed wasm module caching issue
Included hash in wasm file.
Added a manifest file that contains the wasm file name for worker access.
Reworked worker setup to query the manifest file without caching, ensuring the correct wasm file name is always retrieved.
The worker will first attempt to retrieve the cached wasm file, but will refetch it with a cache reload if an error occurs.
