Archetype_DNA_Authoring

Step 5 of the Archetype Builder pipeline. Manually craft the system_dna artifact for the new archetype. The DNA encodes identity (with name=null — instance names come from MIND_Awaken mindName param, not baked into DNA), cognition (values, traits, decision policy, sacred values, taboos), expression (tone, lexicon, formality, formatting tuned to primaryUserPersona), and the evergreen dependencies block that pins every registered skill (by skillArtifactId), schema (by schemaArtifactId), and app (by appName + version + role). Bypasses MIND_PersonaStudio entirely. The dependencies block is the wiring contract — the orchestrator and the archetype's first-cognition skill use it to auto-equip everything. Backstory must be archetype-flavored, not instance-specific. After registration, advance brief.status from 'skills_authored' to 'dna_authored' and hand off to Awaken_And_Verify.
