 * `AgentRunner` over `opencode serve` — a headless HTTP server (the same one
 * the opencode TUI talks to) with an SSE event stream. One server per session,
 * bound to the run's `cwd` (worktree), gives OpenCode the same multi-turn shape
 * as the Claude runner: each `sendMessage` posts another prompt to the same
 * session (history is kept server-side), `session/abort` cancels, and reusing
 * the session id resumes for "Continue".
 *
 * Auth = the host's opencode config/logins. The agent runs autonomously
 * (auto-approved permissions); OpenCode has no per-tool allowlist, so
 * `spec.allowedTools` is ignored. `spec.model` is `provider/model`.
