feat: complete Rust migration with modular architecture

Major changes:
- Migrate Python/shell scripts to Rust modules:
  - analytics/extract.py → src/analytics/extract.rs (ReportExtractor)
  - analytics/analyze.py → src/analytics/analyze.rs (DealAnalyzer)
  - scripts/mqlcompile.sh → src/compile/mql_compiler.rs (MqlCompiler)
  - scripts/backtest_pipeline.sh → src/pipeline/backtest.rs (BacktestPipeline)

- New modular structure:
  - src/models/ - Config, Deal, Metrics, Report structs
  - src/analytics/ - Report parsing and deal analysis
  - src/compile/ - MQL5 compilation via Wine
  - src/pipeline/ - 5-stage backtest orchestration
  - src/tools/ - 27 MCP tool definitions and handlers

- Remove PyInstaller setup (now pure Rust)
- Remove migrated shell scripts (backtest_pipeline.sh, mqlcompile.sh)
- Add GitHub Actions CI/CD for macOS & Linux releases
- Update all documentation for Rust architecture

Binary size: 4.3MB (no Python dependencies)
Tools: 27 MCP tools fully functional
