docs: update README.md and AGENTS.md for new files

Update documentation to reflect new project structure
and files created for test coverage enhancement.

README.md:
- Add STATUS.md link to documentation table
- Add JOURNAL.md link to documentation table
- STATUS.md: Manager-facing status report
- JOURNAL.md: AI agent memory and ADRs

AGENTS.md:
- Document STATUS.md purpose and maintenance
- Document JOURNAL.md purpose (AI memory, ADRs)
- Add tests/system/ directory to project structure
- Clean up obsolete file references
- Update documentation structure section

These changes ensure all team members (human and AI)
understand the purpose and location of key files.
