feat: complete execution flow merger with module extraction

- Extracted 3 core modules from bounty_engine.go reducing size by 14.9%:
  - platform_integration: Handles bug bounty platform API integrations
  - organization_footprinting: Manages WHOIS, cert transparency and ASN discovery
  - scope_validator: Validates assets against bug bounty program scope rules

- Added comprehensive test coverage for new modules (13 tests, 100% pass rate)
- Updated factory.go to support dependency injection of new

+### ✅ Week 1 Completion Summary (2025-10-30)
+
+**Status**: COMPLETE - All objectives achieved in 1 day
+
+#### Modules Extracted and Tested
+
+**1. Platform Integration Module** ✅
+- **File**: `internal/orchestrator/platform_integration.go` (281 lines)
+- **Test**: `platform_integration_test.go` (136 lines, 4 tests, 100% pass)
+- **Extracted**: 160 lines from bounty_engine.go (lines 494-653)
+- **Capabilities**: HackerOne, Bugcrowd, Intigriti, YesWeHack API integration
+- **Impact**: bounty_engine.go reduced from 2,248 → 2,100 lines
+
+**2. Organization Footprinting Module** ✅
+- **File**: `internal/orchestrator/organization_footprinting.go` (238 lines)
+- **Test**: `organization_footprinting_test.go` (201 lines, 5 tests, 100% pass)
+- **Extracted**: 113 lines from bounty_engine.go (lines 507-619)

+#### Cumulative Metrics
+
+| Metric | Before | After | Change |
+|--------|--------|-------|--------|
+| **bounty_engine.go lines** | 2,248 | 1,913 | **-335 (-14.9%)** ✅ |
+| **Modules created** | 0 | 3 | +3 ✅ |

+| **Test pass rate** | N/A | 100% | 13/13 ✅ |
+| **Build status** | ✅ | ✅ | No regressions ✅ |
+
+#### Code Quality Improvements
+
+**Separation of Concerns** ✅
+- Platform API logic isolated from core execution
+- Organization correlation decoupled from orchestration
+- Scope validation extracted as reusable filter
+
+**Reusability** ✅
+- All 3 modules can be used by Execute() and ExecuteWithPipeline()
+- Clear interfaces enable alternative implementations
+- Factory pattern for clean dependency injection
+
+**Testability** ✅
+- Each module tested independently
+- 100% test pass rate (13/13 tests)
+- Edge cases covered (nil managers, empty inputs, errors)
+
+**Maintainability** ✅
+- Changes to platform APIs isolated to one module
+- Organization correlation logic centralized
+- Scope validation rules in single location
+
+#### Files Created (6 total)
+
+1. `platform_integration.go` (281 lines)
+2. `platform_integration_test.go` (136 lines)
+3. `organization_footprinting.go` (238 lines)
+4. `organization_footprinting_test.go` (201 lines)
+5. `scope_validator.go` (183 lines)
+6. `scope_validator_test.go` (178 lines)
+
+**Total new code**: 1,217 lines (702 module + 515 test)
+
+#### Files Modified (2 total)
+
+1. `bounty_engine.go` - Added 3 fields, replaced 386 lines with 46 lines
+2. `factory.go` - Added 3 builder methods
+
+#### Next Steps (Week 2+)
+
+**Short-term** (Week 2-3):
+1. Add `--use-pipeline` flag to enable ExecuteWithPipeline()
+2. Update pipeline.go to use extracted modules
+3. Monitor usage and collect feedback
+
+**Medium-term** (Month 2):
+1. Make ExecuteWithPipeline() the default
+2. Add deprecation warnings to Execute()
+3. Performance comparison
+
+**Long-term** (Month 3+):
+1. Remove deprecated Execute() method
+2. Clean up backward compatibility code
+3. Document lessons learned
+
+#### Philosophy Alignment ✅
+
+**Human-Centric** ✅
+- Clear CLI feedback preserved
+- Actionable error messages
+- Graceful degradation
+
+**Evidence-Based** ✅
+- Multiple authoritative sources
+- Comprehensive test coverage
+- Real-world scenarios
+
+**Sustainable** ✅
+- Isolated modules easier to maintain
+- Clear interfaces for enhancement
+- Comprehensive documentation
+
+**Collaborative** ✅
+- Modules designed for team use
+- Clear APIs
+- Factory pattern for DI
