feat: add Economy Designer + improve Reality Checker & SEO Specialist (#748)

Consolidated landing of three gated contributions:

- Economy Designer (game-development) — virtual economy specialist:
  currency systems, sources/sinks, monetization modeling, inflation
  control, live economy tuning. Distinct from the generalist Game
  Designer. (#651, @blockersiontko)
- Reality Checker — add the missing "Critical Rules You Must Follow"
  section, filling a canonical-template gap. (#746, @a01066983478-lgtm)
- SEO Specialist — add a Pre-GSC keyword-cannibalization audit and
  hreflang implementation template (URL inventory, query-intent overlap,
  title/H1 deconfliction, canonical/language hygiene). (#747, @kyle1188)

README roster row added for Economy Designer; Hermes generated count
269 -> 270. All guards green (divisions/tools/runbooks/hermes-plugin/lint).

Closes #651
Closes #746
