feat(chess/modifiers): add 3 recipes showcasing new trigger primitives (T26)

Browse source 
Adds three recipes to the built-in template library, each built on a
Wave 2 trigger that previously had no pre-composed example:

- Kamikaze Knight — on-captured with target: attacker, nested
  add-to-attribute Hp -2. Death-rattle that damages whichever piece
  made the fatal capture.
- Berserker Pawn — on-move nested with add-to-attribute AttackBonus
  +1. Stacking rage: the pawn grows stronger with every move it
  survives.
- Promotion Feast — on-promotion nested with seed-attribute Hp 5.
  When a pawn finally promotes, it starts its new life with a fresh
  5 HP pool regardless of damage taken on the way up the board.

Each recipe passes validateCustomDescriptor and lands in the editors
Templates dropdown alongside the existing five. Recipe count: 5 → 8.
