Summary by cubic

Cleaned up CI workflows: simplified branch filters, added push runs, set release default to patch, and standardized the sponsor block PR title.

• Description

  • Simplified run-ci triggers: run on push and pull_request; exclude "sponsors".
  • Updated release-branch to remove "auto" and default to "patch".
  • Standardized sponsor block PR title to "chore(docs): update sponsor block".
  • Only GitHub workflow YAML files changed.

• Testing

  • No tests changed; none needed.
  • Validate by pushing and opening PRs (ensuring "sponsors" is excluded), confirming the release workflow defaults to patch, and checking the generated sponsor block PR title.
