chore(release): bump to v2.0.1 (#314)

Patch release rolling up two content updates that just landed:

- ai-seo (#313): aligned with Google's official AI features optimization
  guide — Google's stance, query fan-out, agentic experiences (UCP),
  what-not-to-do, Search Console expectations; reframed
  llms.txt/pricing.md/schema as "not required by Google but helpful for
  non-Google AI engines"; moved content-type tactics to
  references/content-types.md
- image (#311): refreshed model lineup to current May 2026 releases —
  Nano Banana family, Flux Pro 1.1 + Kontext, Ideogram 3.0, ChatGPT
  Images 2.0, Midjourney v7, Recraft V3, SD 3.5 / SDXL
- video (#311): refreshed model lineup — Sora 2 promoted from
  limited-availability caveat, Kling 2.5/3.0, added Seedance, Hailuo /
  MiniMax, Hunyuan Video / Wan 2, Pika 2.x; new "Quick picks" guide

No new skills, no breaking changes. Only the three affected SKILL.md
files bumped to 2.0.1; the other 37 stay at 2.0.0.

- marketplace.json: 2.0.0 → 2.0.1
- VERSIONS.md: ai-seo, image, video rows bumped; 2.0.1 changelog entry
  added
- skills/{ai-seo,image,video}/SKILL.md: metadata.version → 2.0.1

All 40 skills pass validation. sync-skills.js still no-op.
