Handshake58

Reviewed identity overlay because the official repositories and website identify Bittensor SN58 as Handshake58 while native chain metadata previously displayed Pending. On-chain SubnetIdentitiesV3 has since resolved from Pending to native_name "greevils", consistent with the team's already-tracked social.x handle (x.com/greevils_ai) -- Handshake58 is the product/marketplace brand, Greevils is the operating team; not a discrepancy. This re-review pass removed a duplicate surface (the placeholder-named "Pending community data-artifact" and the properly-named skills-api surface both hit /api/skills with identical results, total=63 either way; kept the skills-api one) and gave the other placeholder-named surface ("Pending community subnet-api", /api/agent) a proper name and description. Diffed the current 4-path OpenAPI schema: all routes were already tracked.
