fix: add npm provenance and fix core peer dependency version

Add --provenance flag to npm publish for supply chain security.
Add id-token: write permission to release workflow for OIDC-based
provenance attestation. Fix MIN_CORE_VERSION to dynamically use
current version instead of hardcoded ^8.0.2.
