refactor: migrate documentation structure from agent-docs to rantflow

- Rename agent-docs/ directory to rantflow/ across the codebase
- Update all references in documentation and configuration files
- Add new kanbanStore for task board state management
- Remove deprecated documentation files in MDX format
- Update locale files with new directory naming
- Maintain backward compatibility in file system watchers

This change restructures the documentation-driven development workflow to use the new rantflow/ naming convention while preserving all existing functionality.
