add bench 102 token-quote-coverage (draft)

[Flotapponnier]

Summary

• New bench № 102: token-quote-coverage — measures what % of newly-launched tokens each DEX aggregator can return a valid swap quote for
• 7 launchpads: Pump.fun, Virtuals, Four.meme, WOW.XYZ, Moonshot, Meteora DBC, Clanker
• 6 providers: Mobula, Jupiter (SOL), KyberSwap (EVM), 1inch (EVM), OKX DEX, Odos (EVM)
• Token universe sourced from Dexscreener (neutral third-party, avoids self-reference bias)
• Status: draft — harness not yet built, spec ships first for editorial review
• Bumped cache keys: bench-unfiltered-v47 → v48, all-benchmarks-v50 → v51

What needs to happen before going live

1. Build harness harnesses/token-quote-coverage/ (Go or TS, new service on VPS or Railway)
2. Implement Dexscreener latest-pairs poller per launchpad factory address
3. Implement quote adapters for each provider (can reuse evm-swap-quoting adapters for EVM)
4. Ship harness + flip status: draft → status: live

Test plan

• /benchmarks/token-quote-coverage renders draft placeholder on staging
• Bench appears in home page bench list
• No 404 on direct URL hit after cache key bump propagates
