Add bundled-bestiary mechanism for shipping creatures with the app

D&D creatures listed in data/bestiary/dnd-bundled.json are now merged into
the search index and pre-loaded into creatureMap, so they appear alongside
5etools creatures with no "Load source" step. Source codes are derived from
the JSON itself (each creature carries source + sourceDisplayName), so adding
a new book is a pure data change. Bundled sources are excluded from
getAllSourceCodes() so bulk-import skips them, and they never appear in the
source manager (which only lists cached sources).

Includes a reference extractor (scripts/extract-great-labors.py) for the
5.5e revised stat-block format and a /bundle-bestiary skill that future
agents can follow to add monsters from other PDF books.
