Rewrite SKILL.md to be a pure router per workflow-skill design rules:
- description: trigger conditions only (AP-20). Entry triggers + explicit
anti-triggers naming each i2s-* sub-skill.
- 3 numbered phases (intent / precondition / hand-off) with entry/exit
criteria (AP-6, AP-7).
- Routing pattern with 8 paths: 7 hand-offs to i2s-* sub-skills + 1
cross-cut workflow (review-iterate) kept internal.
- Reference set reduced to router-essentials: routing-table.md (new),
kommunikationsregeln.md, artefakt-pipeline.md.
- Tools narrowed to read/write/edit/glob/grep/ask/todo.
Add references/routing-table.md with trigger -> sub-skill mapping,
precondition rules, hand-off message format, sequence diagram, and
anti-trigger guards.
Vestigial refs (methodik.md, export-formate.md, recherche-regeln.md)
and templates/prototyp-remixer-auswertung.md remain in router for now;
they will be removed in step 10b after sub-skill extraction so any
inter-step git mv preserves rename detection.
Step 3 of i2s-skill-split refactor.
