Cold Email Onboarding — first-run setup

Walks the operator through 10 minutes of setup that makes every downstream output 10x more useful than generic framework prose.

Activation

Loaded automatically by cold-email (the orchestrator) on first invocation when brand-config.json and/or SOUL.md are missing from the project root.

Also user-invocable on demand:

• "Set up brand config"
• "Configure my voice"
• "Re-run cold-email onboarding"
• "Update brand-config"
