docs(maker-platform): flag the audit's unaddressed gaps as honest backlog items (memo §14 + PR-FAQ)

Gap-analysis pass surfaced genuine, *unacknowledged* holes in both docs.
Rather than invent legal/strategy positions, flag them as scoped open work
in the memo's §14 backlog (matching its style) and acknowledge them in the
PR-FAQ's 'what got left out' answer:
- international tax & cross-border (EU VAT/OSS, deemed-supplier, PSD2/SCA,
  KYC/OFAC) — the US-only §11 has a real hole under a digital-heavy global
  beachhead
- infosec & breach posture for the cross-tenant graph (belongs in the §12
  funded reliability core)
- content moderation beyond authenticity (third-party IP / DMCA)
- verification *methodology* (the evidentiary act, treated as a primitive)
- support/dispute operations as a funded F-term
- competitive engagement vs creator-commerce tools (Gumroad/Payhip/Ko-fi/
  Fourthwall/Lemon Squeezy)
- plus lower-priority notes (cuttle substance, catalog-sync at scale,
  accessibility, certification mark, wind-down plan, team capacity)

 The memo's full depth on trust-&-safety/accountability (§10), the complete
