feat: ollama-proxy — multi-account Ollama Cloud reverse proxy
Go reverse proxy for ollama.com that balances requests across multiple API keys with round-robin and failover on 429/5xx. Exposes both native Ollama API (/api/*) and OpenAI-compatible (/v1/*) passthrough. - Round-robin balancer with per-account cooldown (60s default) - Pre-stream failover: 429 → cooldown + next account; 5xx → next account - Streaming invariant: once 2xx starts streaming, no account switch - SSE (text/event-stream) and NDJSON passthrough with http.Flusher - CLI: accounts add/list/remove/set-base-url, serve, version - Accounts stored in ~/.config/ollama-proxy/accounts.json (chmod 0600) - systemd unit (User=dueattendant149, 127.0.0.1:11435, Restart=always) - 43 tests (unit + integration with httptest upstream) - opencode integration: custom provider 'ocp' with explicit model list - Requires NO_PROXY=127.0.0.1,localhost when HTTP_PROXY is set
