Major refactor: Streamline EA structure and fix compilation errors

- Consolidated all trading logic into single SniperEA.mq5 file
- Fixed all compilation errors (0 errors, minimal warnings)
- Removed complex modular structure that was causing issues
- Added comprehensive pattern detection (OB, BOS, FVG, Liquidity Sweeps)
- Implemented multi-timeframe analysis framework
- Added VS Code configuration for MT5 development
- Created implementation plan for completing core trading logic
- Added validation report and build scripts
- Backup original working version as SniperEA_backup.mq5

Status: 45% complete - Pattern detection working, core trading logic pending
