ci: add native linting and exclude CHANGELOG.md from lint

- Add lint:spotless task for Java format checking
- Add lint:fast grouping (super-linter + links + bom + example-poms + spotless)
- Add native-lint task (NATIVE=true, no container needed)
- Switch pre-commit to NATIVE=true mise run lint:fast
- Exclude generated CHANGELOG.md from super-linter and lychee

Depends on grafana/flint#107 (NATIVE env var) and
grafana/flint#112 (v8.5.0 version mapping).
