fix(examples): each example NPC its own outfit, every item at full durability (D323, D324)

The 9d player walk found the example kits looked alike and shipped broken armour.

- D323: the raider wears scrap armour, the camp guard metal, the sniper hide, the
  Juggernaut heavy plate. Weapons are unchanged.
- D324: Kits sets an item's condition straight from its file, and the writer put 0 on
  armour (heavy plate 0 of 1000) and a flat 100 on weapons (an M249's maximum is 500).
  Each item is now written at this Rust's own maximum for it, read from the item
  definition; 0 where the item has none.
- The harness checks it: s6.examples.fullCondition.
