Pin all cosign public key references to the immutable commit hash
(0112e53) that first introduced the key, instead of fetching it from
the release tag. This addresses the concern that an attacker with push
access could replace the key on main/tags and re-sign tampered images.
Docs now show two verification methods: commit hash (recommended) and
release tag (convenience), with explanation of why the hash is stronger.

- Create release as draft first, then publish atomically to avoid partial-release state
- Pin cosign.pub URL to release tag instead of main branch
