Unit 15.20: Fix CI/CD pipeline dependency gaps and align with local 100% test success rate

- Added critical dependency installs (strands-agents, boto3, markdown-it-py, pytest) to both test_coderipple and test_lambda jobs in coderipple-ci.yaml
- Downgraded pipeline Python version from 3.13 to 3.12 for consistency with local testing
- Added error handling for missing requirements.txt
- Documented all changes and rationale in 015_troubleshooting_020.md
- Resolves the CI/CD test failures seen after Lambda import fixes in Unit 15.17–15.19
- Expected result: CI/CD test jobs now pass with 100% success, matching local test runs
