Return the directory where this project's graph data lives. Resolution priority: 1. Registry entry for this repo (set via --data-dir) 2. CRG_DATA_DIR environment variable (global override) 3. Default: /.code-review-graph/ By default, `` /.code-review-graph``. If

    3. Default: <repo>/.code-review-graph/

    By default, ``<repo_root>/.code-review-graph``. If the
    ``CRG_DATA_DIR`` environment variable is set, it is used verbatim
    instead — letting you keep graphs outside the working tree (useful
    for ephemeral workspaces, Docker volumes, or shared caches). See: #155

    The directory is created if it does not already exist; an inner
    ``.gitignore`` (with ``*``) is written so any accidentally-nested
    files never get committed. Both are idempotent.
