Adds the Sasquatch Pro supporter pass with strong, forge-resistant
verification bound to the paying user's npub — no backend required.
Verification (useSasquatchPro):
- STRONG: NIP-57 zap receipt (kind 9735). Purchase signs a zap request
tagged pro-tier/pro-expiry; the receipt embeds it, cryptographically
binding payment → identity (unforgeable by the user).
- FALLBACK: self-signed kind-32671 receipt so paying users are never
locked out if the provider emits no zap receipt.
- Platform owners always Pro. Access = max unexpired expiry.
Purchase (usePurchasePro):
- Zap to skatespots@minibits.cash (falls back to plain invoice), pay via
NWC → WebLN → manual QR. Publishes the fallback receipt on success.
Pricing (sasquatchPro.ts): 4 tiers — 7d/2k, 1mo/5k, 3mo/12k (popular),
1yr/36k sats.
UI (SasquatchProDialog): upgrade sheet with tiers, perk list, QR
fallback, "already Pro" state, extend flow.
Gating (SasquatchGuide):
- Personal tools (get_my_*) now require login + Pro; prompt only exposes
them to Pro users; tool switch guards with a pro_required nudge.
- ⚡ Pro badge when active, ⚡ Go Pro button otherwise; local upgrade
nudge for "my/mine" questions from non-Pro users.
Docs: kind 32671 + verification model documented in NIP.md.
