roast: fix refusal prompt, add Cole/Nathan lore, expand known users

- Reframe prompt as a consented comedy roast between friends so the
  model doesn't refuse on safety grounds
- Add lore for lonely (Cole, 23, dishwasher, gamer) and
  natcofragomatic (Nathan, DCO Tech 3 at AWS, ginger, tape-drive nerd)
- Use a lookup table (_ROAST_LORE) so adding new users is one line
