docs: add honest achievability analysis for 1% market capture

Commit notes

Reality check on hitting 5-10k users: - 5k users = 14 new users/day for a year - 10k users = 27 new users/day for a year

Realistic timeline: 12-18 months with consistent effort - Month 1-3: 500 users (friends, social) - Month 4-6: 1,500 users (content, Discord) - Month 7-9: 3,500 users (word of mouth) - Month 10-12: 6,000 users (flywheel)

Main challenge: Discovery, not product What accelerates: Viral content, influencer adoption, competitor drama

Honest answer: Achievable, not guaranteed, requires 12-18mo commitment.
