ecosystem: add eltociear Security APIs (tokenguard, skill-audit, contract-guard)

[eltociear]

Adds a Services/Endpoints ecosystem entry for three live, pay-per-call x402 APIs (USDC on Base, no signup — wallet is auth):

• tokenguard — ERC-20 rug/safety scanner (mint, blacklist, pausable, tax, upgradeable-proxy, ownership) + onchain-intelligence suite. $0.005/call.
• skill-audit — scans MCP servers & AI-agent skills for 68 malicious patterns (prompt injection, exfiltration, unsafe exec). $0.01/call.
• contract-guard — EVM contract/token risk check across 6 chains. $0.005/call.

All return HTTP 402 with x402 v2 payment requirements and are indexed on x402scan / CDP Bazaar. Adds partners-data/eltociear-security-apis/metadata.json + logo. Verified live at submission time.

Free public readiness snapshot for ecosystem: add eltociear Security APIs (tokenguard, skill-audit, contract-guard):

• Public signal: Public GitHub candidate ecosystem: add eltociear Security APIs (tokenguard, skill-audit, contract-guard) #211: ecosystem: add eltociear Security APIs (tokenguard, skill-audit, contract-guard). Matched R1 terms: api, auth, bazaar, mcp, payment, server, servers, service.
• R1 fit: api, auth, bazaar, mcp, payment, server, servers, service, services, verified, wallet, x402.
• Buyer-agent check I would add before autonomous spend: explicit price/cap unit, policy/version hash, receipt or charge-evidence reference, revocation/dispute path, and allow/caution/block preflight result.
• This separates "interesting paid surface" from "safe for an agent wallet to use".

No invoice, no payment link, no delivery link, no private endpoint; this is only a free public snapshot.
