/**
 * Auto-research handler — sends an auto-research task through the existing
 * AgentBridge (backend proxy) instead of spawning a separate spectral process.
 *
 * This ensures auto-research uses the same model and API keys as the active
 * session — no separate subprocess, no missing API key errors.
 *
 * Flow:
 *   1. Build the auto-research task prompt
 *   2. Ensure session subscriber exists (borrows handleClientMessage pattern)
 *   3. Emit auto_research_start via relay
 *   4. Send task via manager.prompt() — goes through backend proxy with session's model
 *   5. Attach a watcher subscriber to detect turn completion
 *   6. On agent_end, scan for generated extensions and emit auto_research_complete
 *   7. On error, emit auto_research_error
