ci: fix release-drafter duplicate entries and label/prefix mismatch (#79)

- Add autolabeler rules to release-drafter.yml mapping Conventional Commit
  prefixes (feat:/fix:/chore:/docs:/test:/ci:/refactor:) to type:* labels,
  so PRs are categorized from their title rather than requiring manual labels
- Add exclude-labels to each release-drafter category so a PR with multiple
  type:* labels only appears in the first matching section (no duplicates)
- Update labeler.yml with title and head-branch pattern rules matching the
  same Conventional Commit prefixes, keeping file-glob rules as fallback
- Remove .github/** glob from type:chore to prevent CI/packaging PRs from
  being mislabeled when their title indicates a feature (e.g. feat: add APK)

Closes #78 (action items)
