ci: use Angular-style labels in the templates, labeler and release notes

Issue forms add bug or feature with needs triage, the labeler uses area:
labels only, release notes group by change type, and CONTRIBUTING lists
every label.

CONTRIBUTING.md

@@ -29,6 +29,21 @@ By taking part you agree to the [Code of Conduct](./CODE_OF_CONDUCT.md). Report
 - **Docs changes:** follow the [writing guide](./apps/docs/src/content/contributing/writing-docs.md). Run the docs site with `pnpm docs:dev`.
 - **Keep the docs in step with the code:** when a pull request changes behaviour, an option, a UI label or an agent tool, update the matching page in `apps/docs` in the same pull request. If no docs change is needed, add the `no-docs` label and say why in the description. The Docs check workflow warns when code changes without docs.
