Enhance suitability assessment and documentation

- Implemented `check_suitability` method in `CoreReadOnlyRepository` for suitability determination based on customer and product risk levels.
- Added `build_suitability_log_row` function in `suitability.py` for mapping suitability check results to `risk_suitability_log`.
- Updated `AGENTS.md`, `ENVIRONMENT.md`, and `FLOW.md` to reflect changes in suitability assessment processes and documentation.
- Revised `FRAMEWORK.md` and `MEMORY.md` to clarify project structure and data flow related to suitability checks.
- Expanded `TODO.md` with tasks related to logging and auditing suitability assessments.
