Make new-version publish step idempotent on reruns

[Copilot]

The new-version GitHub Actions job failed in npm publish with TLOG_CREATE_ENTRY_ERROR (409) when attempting to publish package versions that were already recorded. This change updates the release publish mode to avoid failing on reruns/duplicate publish attempts.

• CI release publish behavior

  • Switched Lerna publish in scripts/github/deploy.sh from from-git to from-package.
  • This aligns publishing with package registry state (publish only versions not already present), reducing rerun fragility in new-version.

• Scope

  • Single-line change in release automation script.
  • No changes to version calculation, tagging, changelog generation, or branch push behavior.

# scripts/github/deploy.sh
- lerna publish --registry=https://registry.npmjs.org/ from-git --yes --pre-dist-tag rc --no-verify-access
+ lerna publish --registry=https://registry.npmjs.org/ from-package --yes --pre-dist-tag rc --no-verify-access
