Initial commit: MT5 EA Optimizer v1.0

Full optimization system for LEGSTECH_EA_V2:
- Flask + SocketIO live dashboard (dark premium UI)
- MT5 process control (auto-kill, clean launch, retry)
- HTML report parser (UTF-16 LE, 597 trades, metrics)
- Pre-run validation and actionable error messages
- Analysis engines: Reversal, TimePerfomance, EntryExit, EquityCurve
- Composite scoring (Calmar-primary)
- Mutation engine with knowledge_base.yaml
- Validation gate: IS + Walk-Forward
- Reports folder with HTML/CSV per run
- Double-click launcher batch file
