refactor(compose-solution): remove patent examples from phase files

After merging feat/compose-solution, 3 phase files still referenced
patent-scale research / patent block suffix / sensitive IP question. Strip
those generic-kit-incompatible examples:
- phase-2-decompose.md: "patent-scale" → "deep-domain"
- phase-6-block-augment.md: "<slug>-patent" disambiguator → "<slug>-embedded"
- phase-7-assemble.md: drop sensitive IP from fields passed to new-agent wizard

Final grep for "patent" in main tree: zero hits.
