/**
 * Phase 17 integration smoke — "play song" loop architectural verification.
 *
 * Proves the loop closes end-to-end for the bundled CDP plugin path:
 *
 *   1. Bundled restore copies aiden-plugin-cdp-browser into the user dir.
 *   2. PluginLoader discovers it. State: pending-grant (no granted file).
 *   3. /plugins grant — running on the loaded registry — writes the
 *      granted-permissions file and reloads. State: loaded.
 *   4. Tools `browser_real_click`, `browser_real_extract`, `browser_real_eval`
 *      are reachable via ToolRegistry.buildExecutor and dispatch into the
 *      plugin's CdpClient (mocked via criFactory injection — no Chrome).
 *   5. Simulating the agent's tool sequence on a "play song" prompt
 *      (open_url → browser_real_click on a /watch?v= URL), we verify
 *      every wire reaches the right place.
 *
 * What this does NOT verify:
 *   - Real LLM behavior (no live API calls; cost discipline = $0).
 *   - Real Chrome attach (requires user's machine; manual user smoke).
 *
 * Real-LLM + real-Chrome verification is the manual user pass per
 * Phase 17 spec ("actual real-Chrome playback verification is for
 * manual user smoke"). This test is the architectural-completeness
 * gate that runs on every commit.
