fix: simplify release to workflow_dispatch (no bot commits needed)

Replace the two-workflow PR-based release flow with a single
workflow_dispatch trigger, matching the socket-cli pattern.

Changes:
- Remove release-prep.yml (automated version bump + PR creation)
- Make release.yml a manual workflow_dispatch that reads the version
  from Cargo.toml, tags, builds, and publishes
- Add dry-run option to build without publishing
- Use NPM_TOKEN secret for npm publish (fixes ENEEDAUTH on new packages)
- Add registry-url to setup-node for proper auth

Release flow after this change:
1. Bump version in a PR: run scripts/version-sync.sh, commit, merge
2. Click "Run workflow" on Release
3. Done - tags, builds, and publishes automatically

This avoids the signed commit requirement that blocked github-actions[bot]
from pushing to protected branches.
