Update report title to 'The Carry Problem' — sassy but substantive

Changed from: 'How Bad Am I, Actually? Building a Pickleball Rating System That Doesn't Lie'

New title: 'The Carry Problem: When Your Rating Doesn't Match Your Ego'
With subtitle: 'A Mathematically Principled Approach to Rating Pickleball Players
               (And Finally Proving Whether Your Partner Is Holding You Back)'

RATIONALE:
- 'The Carry Problem' directly addresses v2's innovation (effective opponent formula)
- Funny and relatable without being mean-spirited
- Hooks both casual players and technical readers
- Self-deprecating sass matches the rec pickleball vibe
- More memorable than academic title

The rest of the document (intro, TL;DR, content) already had the right tone.
