Overview

The slice of coderag.yml msnav needs: where the workspace is and where the index lives. Resolution mirrors coderag's load_config so both daemons agree on the db path for any given hub:

workspace_root:  explicit arg > coderag.yml's key > "." (the cwd — the
               lifecycle commands always run the daemon with cwd=hub)
storage_dir:     declared (workspace-relative unless absolute)
               > legacy <workspace>/.coderag when it already holds a db
               > the package data dir (~/.local/share/coderag/hubs/<hub>)

All other coderag.yml keys (models, profiles, …) belong to the indexer and are ignored here — msnav never indexes.
