feat: Per-combo reset options and preserve-position toggle

- Per-combo reset when: Game timer (default), Never, On target change,
  After X seconds. Never = cycle sequence without time/target reset.
  After seconds uses configurable 0.5–300s window.

- Per-combo 'Preserve position when using other actions' (default on):
  when on, using another combo or any ability never resets this combo's
  step; it only resets per its own 'Reset when' setting. When off
  (original), using an action not in this combo resets it to step 1.

- Optional ITargetManager via constructor for On target change; plugin
  loads if service unavailable (On target change no-op when null).
