Add name dictionary with 10 themed categories

Create name_dictionary.json with 175 words each across mythology, food,
space, nature, warriors, music, literature, gems, ocean, and weather
categories. Words are short (<= 12 chars), title-cased, and suitable as
Pokemon nicknames. No intra-category duplicates; cross-category overlap
is intentional.
