chore: suppress release.yml false-failure notifications on non-tag pushes

[SmartBrandStrategies]

The release.yml workflow triggers on push: tags: v* but GitHub Actions still evaluates the workflow file on every push to main. When no tag matches, it reports "no jobs were run" which GitHub treats as a failure — sending a notification email every time.

Options

1. Move the workflow trigger to workflow_dispatch only (manual releases)
2. Add an explicit branches-ignore: ['**'] under the push trigger to prevent non-tag evaluation
3. Adjust GitHub notification settings to not notify on skipped/empty runs

This is a low-priority noise reduction issue but contributes to notification fatigue.

Fixed by cc_task f065fbe2. Added branches-ignore: ['**'] to release.yml to suppress false-failure notifications on non-tag pushes.
