/**
 * Built-in ACP harness presets.
 *
 * These register convenient defaults for known ACP-compliant local coding
 * agents. Each preset's command/args are overridable through the resolve
 * config, e.g.
 *
 *   resolveAgentHarness("acp:gemini", { command: "gemini" });
 *
 * The default commands launch the agents through `npx` so they work without a
 * prior global install. They are documented and overridable because agent CLIs
 * still evolve their ACP entry flags.
