fix: update Dune service description

[va3093]

Summary

• Updates the Dune service description in services.ts to better reflect the full scope of available data
• Regenerated discovery.json and llms.txt

Before

Execute SQL queries on Dune and retrieve results or CSV exports from completed executions.

After

Query across raw transaction data, decoded smart contract events, stablecoin flows, RWA tracking, protocol analytics, DeFi positions, NFT activity, blockchain market research, and whatever is trending in cryptocurrencies.

Note: discovery.json drift

The regenerated discovery.json includes a few unrelated changes to the QuickNode service (categories, intent, description fields). This is pre-existing drift between services.ts and the committed discovery.json on main that surfaces when the generator runs.

👋 Thanks for submitting a service to the MPP directory!

If you want your service included in the curated mpp.dev/services list, complete this checklist before review:

Required

• Your service is live and accepting payments via MPP (not a placeholder or coming-soon)
• You've added your entry to schemas/services.ts following the contributing guide
• Types pass: pnpm check:types
• Build succeeds: pnpm build

Recommended

• Register your service on MPPScan (by Merit Systems) — it follows the standard MPP discovery format and makes your service discoverable by agents immediately, no PR required

Review criteria

We prioritize services that are high quality and novel. We may not approve services that duplicate existing functionality or aren't yet production-ready.
