/**
 * Tests for `wakeAgentForOpportunity()` — the generic internal agent-wake
 * mechanism.
 *
 * Exercise strategy: the wake helper takes a `resolveTarget` dependency that
 * yields a live `Conversation`. These tests build a lightweight structural
 * double typed as `Conversation` (`makeWakeConversation`) that stubs only the
 * handful of members the wake touches — `getMessages`, `messages.push`,
 * `isProcessing`/`setProcessing`/`waitForIdle`, `currentTurnTrustContext`,
 * `setSubagentAllowedTools`, `kickDrainQueue`, `maybeCompact`,
 * `contextWindowManager.estimateInputTokens`, and a scripted `agentLoop.run()`.
 *
 * The wake's side effects flow through the daemon boundary, so the
 * instrumentation is captured at that boundary: event emission and the
 * ui_surface card via the `broadcastMessage` module mock, and tail
 * persistence via the `addMessage` module mock. Each double registers itself
 * in `wakeConvRegistry` keyed by `conversationId` so those module mocks can
 * route captured calls back to the originating conversation's probe arrays.
