Adds references/partnership-types.md covering the five partnership types
from Founding Marketing Ch. 11 — integrations, reseller, affiliate,
co-marketing, and app store/marketplace — with flagship stats (HubSpot
$100M ARR / ~40% of revenue / 3,400+ partners) and standout moves
(Calendly's staged ladder, 20/80 affiliate power law, buyout clauses,
Notion's permissionless co-marketing, Grammarly 0→10M). Wires the
reference into SKILL.md routing with a summary table, adds eval id 7,
bumps co-marketing to 2.0.1 and updates the VERSIONS row.
Affiliate coverage stays at the partnership-strategy level; mechanics
remain in the referrals skill.
