Addresses three gaps where Claude Code and Gemini CLI outperform Manual Slop's
MMA during actual execution:
1. Live worker streaming: Wire comms_log_callback to per-ticket streams so
users see real-time output instead of waiting for worker completion.
2. Per-tier model config: Replace hardcoded get_model_for_role with GUI
dropdowns persisted to project TOML.
3. Parallel DAG execution: asyncio.gather for independent tickets (exploratory
— _send_lock may block, needs investigation).
4. Auto-retry with escalation: flash-lite -> flash -> pro on BLOCKED, up to
2 retries (wires existing --failure-count mechanism into ConductorEngine).
7 new tasks across Phase 6, bringing total to 30 tasks across 6 phases.
