- Added find_configs_directory() to use same logic as API (api/configs_repo/official first, then configs/)
- Added list_all_configs() to display all 24 configs grouped by category with descriptions
- Updated CLI to support --all flag, making config argument optional when --all is used
- Added 2 new tests for --all flag functionality
- All 51 tests passing (51 passed, 1 skipped)
This enables users to discover all available preset configs without checking the API or filesystem directly.
