docs(cli): list dependency ranking config

search_graph already reads search_disable_dep_ranking, and the MCP schema names that config key. Add it to CBM_CONFIG_REGISTRY so config list/get guidance exposes the same setting users see in the API description.

Add a CLI registry regression test for the key, default, range, and dependency-ranking guidance. This does not change search behavior, MCP schemas, DB schema, or tool visibility.

Validated with make -f Makefile.cbm build/c/test-runner, CBM_ONLY_SUITE=cli ./build/c/test-runner, CBM_ONLY_SUITE=tool_consolidation ./build/c/test-runner, git diff --check, and bash scripts/check-source-safety.sh.
