DEKC Init
Create a data-engineering OKF knowledge root.
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/dekc_common.py" init-bundle \
--repo . --bundle knowledge --title "Data Platform Knowledge"
Optionally write .dekc/config.yml from .dekc/config.example.yml.
Depends on: OKF for graph ops, PKC for project reasoning (install companions).
Done when: index.md has okf_version, catalogs exist, bronze/silver/gold layers seeded.
