security: redact hidden retro combos from all public docs

Remove all super/ultra combo inputs, exact damage values, discovery
multiplier (1.5x), and Konami Code from BOT_SETUP.md, bot-guide.md,
docs.ts API, and example bot. Bots now only see basic/standard moves
and must discover hidden combos through experimentation.
