bincraft#33 replaces the cranlike fork: upload_package_index() no longer
keeps a PACKAGES.db and reuses the records of the published PACKAGES.rds
instead, so patching the database stops having any effect.
- patch Built in each slot's PACKAGES.rds, limited to the slot's own rows,
when the installed bincraft no longer loads cranlike
- keep patching PACKAGES.db for releases that still do
- call the internal built_stamp() with `:::`, it was never exported
