feat(cli): default to universal-rigorous-style template when --rule not specified

- Add default template fallback in cli.ts (effectiveRule)
- Update cli-tools-usage.md with English descriptions
- Add ACE semantic search to Pattern Discovery Workflow
- Simplify Template System documentation (list template names only)
- Filter CLI progress messages (auth, loading) in output converter
