Subject: [PATCH] fix: Add WASM artifact verification before publish

Add verification step in release workflow to ensure all WASM artifacts
are present before publishing to npm. This prevents incomplete packages
from being published if any matrix build job fails.

The verification checks for WASM files from all four bands:
- v0_82_87
- v26
- v42
- v48

If any band is missing artifacts, the workflow will fail with a clear
error message before reaching the publish step. This replaces the
silent failure behavior of the previous "cp ... || true" command.
