"""Build-time payload assembly for the delivery-workbench package.

All metadata lives in pyproject.toml; this file exists for one
reason: the distribution contract (docs/distribution.md) ships the
vendorable payload as ``dw_pmo/_payload/`` mirroring the
``pmo-roadmap/`` source layout, so install.sh and update.sh run
unmodified from a checkout or from the installed package. Standard
package-data cannot pull files from outside the package directory,
so a build_py hook copies the payload into the build tree.
