V2 Phase 3: combat rules automation (conditions, damage types, reminders)

Browse Source

Completes the deployable Phase 1-3 chunk: the combat tracker now runs the math.

- condition-effects engine: declarative CONDITION_EFFECTS_5E/PF2E table +
  deriveState(system, speed, conditions) → effective speed / advantage state /
  incapacitation / pf2e status penalty. Tracker shows effect badges
  ("Speed 0", "Disadv. attacks", "−2 status"); pure + 10 unit tests.
- damage types: applyDamage(c, amount, type?) consults snapshotted monster
  DamageDefenses (immune→0, resist→halve, vulnerable→double), back-compatible.
  Monster add snapshots damageDefenses; tracker shows a type picker only when a
  creature has typed defenses, and the log notes resisted/vulnerable amounts.
- concentration + death saves are surfaced as REMINDERS, never auto-rolled:
  damaging a concentrating PC logs "roll a DC N Con save…"; a downed PC's turn
  logs "make a death saving throw." The player rolls and resolves via the Drop
  button / death-save pips they already own. (Per user: no auto dice rolls —
  it removes the player from their character.)

Build + 271 unit tests green. Verified live: grapple → Speed 0 badge;
fire-immune creature shows the immune-labelled damage picker.
