getJson(cid)now reads the gateway URL fromipfs.gatewayconfig (env:IPFS_GATEWAY, default:https://gateway.pinata.cloud/ipfs). Retries up to 3 times with 500ms backoff.getGistContent(id)fetches the gist, readscontent_hash, callsIpfsService.getJson, caches the result in-memory for 5 minutes. Returns 404 if gist/CID missing, 502 if gateway fails.GET :id/contentroute (placed beforeGET :idto prevent route shadowing).IPFS_GATEWAYadded toconfiguration.ts,env.validation.ts, and.env.example.Tests
11 unit tests pass (4 create, 2 findOne, 5 getGistContent: success, cache hit, 404 not found, 404 no CID, 502 IPFS failure).
Closes #606
