beat.mjs embeds a pack's roster verbatim into every area, so adding
beforeInitiative changed the shape of the emitted delve file — and two files
from the same seed could carry different structures under identical stamps.
The change originates in the packs, not in the generator's composition, so it
belongs to catalogVersion rather than GENERATOR_VERSION: the packs are at
schema 2 and a file now stamps barrow@2. The note on GENERATOR_VERSION says
which stamp owns which kind of change, since that was the ambiguity.
README's test counts were still 39 and silent about the adapter suite.
