 * OpenCode CLI runtime — invokes `opencode run --format json`
 * and maps the streaming NDJSON output to {@link AgentEvent} instances.
 *
 * OpenCode uses a per-line envelope model where every NDJSON line has:
 * `{ type, timestamp, sessionID, ...data }`
 *
 * Key differences from other runtimes:
 * - Text events are complete parts (no delta tracking needed)
 * - Tool events combine use + result in a single line (buffered drain pattern)
 * - Usage/cost comes from `step_finish` events
