/**
 * Autoresearch task executor — bridges TaskManager with the
 * autoresearch experiment loop.
 *
 * Each tick:
 * 1. Loads/creates a ResearchWorker for the task's tag
 * 2. Gets the phase-appropriate tool filter
 * 3. Calls NeuroLink.generate() with research tools + prompt
 * 4. Advances phase based on which tools the AI called
 * 5. Returns a TaskRunResult
 *
 * Workers are cached by tag to avoid re-initialization on each tick.
 * Forwards the NeuroLink emitter to each worker for lifecycle events.
