Adds a minimal but real ACP stack for the opencode process: - pkg/config: process.args default ["acp"] (opencodeCommand still "opencode") - internal/process: NewManager(command, args) — exec.Command uses args - internal/acp (new): NDJSON transport + JSON-RPC client over the existing process stdio. Implements initialize / session/new / session/prompt / session/cancel. Serves fs/read_text_file and fs/write_text_file from the workspace's fs.FileSystem. terminal/* requests get MethodNotFound. - internal/service/acp_service: per-workspace Client + mutex; starts the process on first prompt; transparently re-init on restart. - internal/api/acp_handler: GET /acp/status, GET /acp/history, POST /acp/prompt, POST /acp/cancel. - internal/model/acp: API DTOs. - internal/acp/client_test: NDJSON split-lines, request/response correlation, notification dispatch, agent-initiated request handling (fs + terminal). Existing process WS endpoint and Shell subsystem are unchanged. Conversation: 019f354c-a51b-7ec3-83ad-c647e9b50b19
