feat: Smart Autonomous 3-Phase Optimizer — complete redesign

PROBLEM: Old system repeated identical params, all scores flat at 0.2500, user had zero control over symbol/TF/dates. Not smart, not dynamic. NEW ARCHITECTURE: optimizer/ (NEW package) ├── __init__.py ├── session_config.py User choices (EA, symbol, TF, dates, budget, objective) ├── lhs_sampler.py Latin Hypercube Sampling — diverse exploration ├── result_ranker.py Relative scoring (best in session=1.0, worst=0.0) ├── budget.py Time budget tracker └── pipeline.py 3-phase orchestrator Phase 1 — Broad Discovery (LHS, 20-26 runs): Samples FULL parameter space, not just defaults±tiny step LHS guarantees coverage: all 17 optimizable LEGSTECH params explored Relative ranking: profitable configs float top, losers score 0 Phase 2 — Refinement (9 runs): Neighbor search around top 3 configs at ±20% range (not ±0.5 step) Keeps best of Phase1 vs Phase2 — never regresses Phase 3 — Validation (5 runs): OOS backtest on unseen data period Sensitivity test: nudge params ±20%, detect fragility Verdict: RECOMMENDED / RISKY / NOT_RELIABLE Output: Clean downloadable .set file via /download_set/<run_id> UI REDESIGN: ui/templates/landing.html New / homepage (was old dashboard) ui/templates/setup.html New /setup — EA, symbol, TF, dates, budget, objective ui/templates/dashboard.html Updated /dashboard with: - 5-step phase indicator - Real progress bar per run - Phase 1 results table (top 5 after phase1) - Verdict banner with download button - No-profitable-config warning ui/static/js/dashboard.js Handles 8 new pipeline SocketIO events app.py New routes: /, /setup, /dashboard /api/start accepts full SessionConfig JSON /download_set/<id> serves optimized .set ea/registry.py +list_all() for setup page dropdown ui/templates/reports_index.html Back to Dashboard → /dashboard (was /) ui/static/css/style.css +dot-warn, dot-done, profit-pos/neg, aliases FIXES: Score no longer flat 0.2500 (was: absolute thresholds on losing EA) User now controls: symbol, timeframe, dates, budget, objective Parameters now span full range (was: tiny step from defaults) Verdict is actionable: RECOMMENDED / RISKY / NOT_RELIABLE with reason TESTED: 8/8 pre-flight checks pass Browser test: landing ✓, setup form ✓, /dashboard ✓, phase indicator active ✓, /reports ✓, back link ✓

+optimizer/pipeline.py
+The Smart 3-Phase Optimization Pipeline.

+Replaces optimizer_loop.py as the core orchestration engine.
+Receives a SessionConfig → runs Phase 1, 2, 3 → emits SocketIO events.

+Architecture:
+    Phase 1: Broad Discovery    (LHS samples, 20–30 runs)
+    Phase 2: Deep Refinement    (neighbor search around top 3)
+    Phase 3: Validation         (OOS backtest + sensitivity)
