"""
CLI command for discovering and inspecting Cursus pipeline projects.

The ``cursus projects`` command group answers "what pipeline projects exist under this
root, and what does each contain?" — for the ``projects/*`` folders under the
Cursus dev root, or the per-pipeline folders under a consumer repo such as
BuyerAbuseModsTemplate.

A pipeline project is the standard deployable Cursus layout: a configuration directory
(``pipeline_config`` / ``pipeline_configs``) of config JSON files, alongside
``dockers``/``scripts`` and a pipeline-definition module. This command reads each
project's config JSON (no SageMaker/engine objects are constructed), so it is cheap and
safe to run anywhere.

Examples:
    cursus projects list --root ./projects
    cursus projects list --root ~/mods/src/BuyerAbuseModsTemplate/src/buyer_abuse_mods_template
    cursus projects show --root ./projects rnr_pytorch_bedrock
    cursus projects show munged_address_pytorch          # locate by name (generic search)
