fix(workflow): separate release-drafter and autolabeler workflows for v7 compatibility (#366)

- Split release-drafter.yml: triggers only on push to main, uses release-drafter@v7
- Create release-drafter-autolabeler.yml: triggers on pull_request + pull_request_target
  with fork-aware gating to handle same-repo and fork PRs without duplicate runs
- Update permissions: drafter needs contents:write, autolabeler needs pull-requests:write
- Fix commitish: use explicit 'main' instead of dynamic repository.default_branch
- Autolabeler now uses correct release-drafter/release-drafter/autolabeler@v7 action

Fixes PRs not getting auto-labeled after v7 migration
