add AlgoVoi to x402 Facilitators table

[chopmob-cloud]

What this adds

One row in the x402 Facilitators table for AlgoVoi — a multi-protocol (x402 + MPP + AP2) facilitator covering seven mainnet networks: Base, Solana, Stellar, Algorand, VOI, Hedera, and Tempo.

Facilitator	Network	Discovery Endpoint
AlgoVoi	Base, Solana, Stellar, Algorand, VOI, Hedera, Tempo	api.algovoi.co.uk/.well-known/pay-skills.json

Why it fits the table

AlgoVoi has the broadest network coverage of any listed facilitator. The discovery endpoint is the pay.sh-compatible catalog at /.well-known/pay-skills.json — pay.sh's aggregator workflow auto-imports our active tenant resources from this URL (solana-foundation/pay#349).

Verification

curl -s https://api.algovoi.co.uk/.well-known/pay-skills.json \
  | jq '{version, provider_count, base_url, networks: (.providers | map(.fqn | split("/")[0]) | unique)}'
# → version 2 envelope with provider_count, base_url, and the active tenant resources

Notes

• Stellar mainnet xChain shipped today (2026-05-05). First mainnet bridge from Base settled in ~2 minutes; canonical Circle USDC delivered to the merchant's classic Stellar address (any Stellar wallet supports the asset).
• Production-tested on Base + Solana + Stellar with USDC settlement.
• Same facilitator endpoint serves both direct payment (Solana Pay reference / Stellar SEP-7 / etc.) and xChain (EVM USDC bridged to the destination chain via Circle CCTP V2 or Allbridge Core).
