chore: align naga release branch config

[Ansonhkg]

WHAT

• point Changesets CLI base branch at naga
• configure the release workflow to create changeset-release/naga

WHY

• the GitHub Action was resetting to changeset-release/master, which lacks the .changeset directory on this network branch and causes the release job to fail

[Copilot]
