1. Pro purchase confirmation: on a paid pass, send the buyer an encrypted
NIP-17 receipt to their own inbox (tier, expiry, unlocked perks). Best-effort
so it never blocks the purchase. Success toast now points to the DM.
2. Frictionless Pro answers: add local static-FAQ entries for "sasquatch pro",
"pro perks/version", pricing, "go pro", "upgrade" — so those questions are
answered instantly and never dead-end when the free AI model is rate-limited
(the exact failure seen when asking "what perks has the pro version?").
3. FAQ matching now prefers the longest matching key so specific phrases win
over broad ones ("sasquatch pro" > "pro").
4. Refresh the free-model fallback list (add deepseek-v3, gemini-2.0-flash-exp,
qwen-2.5-72b) for better free-tier AI availability.

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.
