conductor: Create 3 MVP tracks with surgical specs from full codebase analysis

Three new tracks identified by analyzing product.md requirements against
actual codebase state using 1M-context Opus with all architecture docs loaded:

1. mma_pipeline_fix_20260301 (P0, blocker):
   - Diagnoses why Tier 3 worker output never reaches mma_streams in GUI
   - Identifies 4 root cause candidates: positional arg ordering, asyncio.Queue
     thread-safety violation, ai_client.reset_session() side effects, token
     stats stub returning empty dict
   - 2 phases, 6 tasks with exact line references

2. simulation_hardening_20260301 (P1, depends on pipeline fix):
   - Addresses 3 documented issues from robust_live_simulation session compression
   - Mock triggers wrong approval popup, popup state desync, approval ambiguity
   - 3 phases, 9 tasks including standalone mock test suite

3. context_token_viz_20260301 (P2):
   - Builds UI for product.md primary use case #2 'Context & Memory Management'
   - Backend already complete (get_history_bleed_stats, 140 lines)
   - Token budget bar, proportion breakdown, trimming preview, cache status
   - 3 phases, 10 tasks

Execution order: pipeline_fix -> simulation_hardening -> gui_ux (parallel w/ token_viz)
