feat(marketing): add professional partner campaign skill

[brs98]

What

Adds a reusable Professional Partner Campaign Launch skill, a preview workflow, a strict company-profile schema/validator, and a WHOOP hackathon case study.

Why

The skill packages verified product facts into a reviewable Portal block and storefront banner proposal for approved coaches, gyms, clinics, and creators while explicitly avoiding recruiting incentives and unsupported medical, earnings, offer, or attribution claims.

How

• validates the active company, Portal identity, profile, catalog projection, and optional existing partner page
• generates an immutable four-file local campaign package or a zero-write dry run
• constrains every workflow step with tool allowlists that exclude APIs, CLI, deploy, and publish tools
• keeps live Portal, banner, MySite, conversion, reward, and retention mutations outside v1 until recorded rollback-safe primitives exist
• includes dependency-free adversarial profile tests and catalog contract tests

How to test

python3 -m unittest discover -s scripts -p "test_*.py"
python3 scripts/validate_catalog.py
python3 marketing/partner-campaign-launch/scripts/validate_profile.py marketing/partner-campaign-launch/references/company-profile.example.json

The workflow also passes Fluid Mist WorkflowDefinitionSchema.safeParse against the current fluid-mono checkout.

Tracking

Hackathon prototype work; no Linear issue.
