feat(T3.5-T3.8): complete feature expansion tasks

T3.5: Custom Judge Implementations
- Add internal/judge package for custom judges
- Implement Judge interface for domain-specific validators
- CustomJudgeRegistry for managing judges
- Register/unregister judges at runtime
- Set default judge
- List all registered judges
- 5 judge tests, all passing

T3.6: Immutable Audit Trail (Enhanced)
- Add internal/audit/immutable_log.go for tamper-proof logging
- SHA256-based hash chaining for integrity
- Immutable append-only entry structure
- Entry sequencing and previous hash tracking
- Verify() for integrity checks
- Metadata storage for extensibility
- 4 immutable log tests, all passing

T3.7: Workflow Composition
- Add internal/composition package for nested workflows
- WorkflowComposer for managing child orchestrators
- ChildOrchestrator representing nested workflows
- Parent-child task relationships
- Status tracking for child workflows
- Hierarchy queries
- 4 composition tests, all passing

T3.8: External Task System Integration
- Add internal/external package for task importing
- TaskImporter for GitHub/Linear/JIRA task import
- Source tracking (github, linear, jira)
- Task status synchronization
- Query by source
- External ID mapping
- 5 external task tests, all passing

T3 Milestone: 8/8 tasks COMPLETE (100%)

Test Coverage:
- T3.5: 5 judge tests
- T3.6: 4 immutable log tests
- T3.7: 4 composition tests
- T3.8: 5 external task tests
- Total T3: 40+ tests across 8 tasks, all passing
- Combined with T1+T2: 240+ tests, zero failures

Architecture:
- Each T3 task is independent package with zero cross-dependencies
- Interfaces enable extension and testing
- Thread-safe concurrent operations
- Minimal external dependencies
- Production-ready implementations

Next: Prepare T1+T2+T3 for squash-merge to main
