Complete Unit 15.5: Final cleanup for Strands Lambda migration

- Removed all references to deprecated layer-based architecture from build-automation.sh
- Completely rewrote comprehensive-validation.sh to align with simplified Strands pattern
- Deleted obsolete environment variables related to layers
- Removed outdated generated reports (validation-report.json, build-report.json)
- Updated documentation (Unit 15.15) to reflect full cleanup scope

Result: CI/CD build and validation infrastructure is now fully aligned with the simplified Strands Lambda function from Unit 15.13. Pipeline is clean, maintainable, and consistent with current architecture.
