/**
 * OpencodeAgentRunner — AgentRunner impl backed by the opencode server.
 *
 * Architectural difference from ClaudeAgentRunner:
 *   - Claude's `query()` runs the whole agent loop IN-PROCESS (tools execute
 *     inside the same Node process as the daemon). That's why ClaudeAgentRunner
 *     can register org tools (org_send, ask_human, …) directly via
 *     createSdkMcpServer.
 *   - opencode runs the agent loop in its OWN server process. The SDK is a
 *     remote client: create a session, POST prompts, read the response.
 *
 * Verified against @opencode-ai/sdk 1.18.x (NOT the docs — the .d.ts and a
 * live probe):
 *   - `createOpencode()` spawns a server and returns { client, server }.
 *   - `client.session.create({ body: { title } })` → `{ data: { id } }`.
 *   - `client.session.prompt({ path: { id }, body: { parts: [{ type: 'text',
 *     text }], system?, model? } })` BLOCKS for the whole turn and returns
 *     `{ data: { info, parts } }` — info carries tokens
 *     ({ input, output, reasoning, cache: { read, write } }) and cost; the
 *     assistant text lives in parts of type "text".
 *   - Because prompt() blocks, undici's default headers timeout (~30s) kills
 *     any real turn with UND_ERR_HEADERS_TIMEOUT. This runner installs a
 *     dispatcher with headersTimeout matching TURN_TIMEOUT_MS — without it
 *     every non-trivial org turn dies.
 *
 * Org tools (org_send, knowledge_search, …) travel over the shared FENCE
 * PROTOCOL (tool-fence.ts): rendered into the system prompt, parsed out of
 * the assistant text, executed in-process, results fed back into the same
 * session — same mechanism as KimiCodeAgentRunner.
 *
 * Non-disturbance guarantees:
 *   - The SDK is imported dynamically; the package has no hard dependency on
 *     @opencode-ai/sdk. Selected only via MONOMIND_RUNTIME=opencode; without
 *     it the Claude path is byte-for-byte unchanged and run() rejects with a
 *     clear actionable error instead of crashing at import time.
