PetPrograms

One Mind program per species and variant, assembled from the catalog's modules and built once, with the settings each module reads as c.settings. A pet instantiates its own copy (Lua state is per pet; compiled code is shared).

A PetPrograms belongs to one catalog load and says each warning once for that load. Use it on the main thread only, and outside Lua Mind callbacks: building a program runs Lua, which inside a callback would share that callback's budget. The first call for a species and variant decides its program; later calls get that program whatever entries and file name they pass.
