CombatStatuses now mirrors every persistent combatState one-shot —
depleting resources (ward/spore/reflect/autocrit/arcane-ward/heal-
charges), once-per-fight class/race/subclass flags, and accumulated
buff stat deltas. resumeTurnEngine restores them; commit writes them
back in place. Fixes turn-based bugs where Orc rage, Halfling Lucky
reroll, and the Assassin first-attack bonus re-fired every round and
Abjuration Arcane Ward did nothing.
Buff spells and buff-type consumables (ward/atk/def/crit/spore/reflect/
auto-crit) are now usable mid-fight: a flattened-delta model diffs the
reused applySpellBuff/ApplyConsumableMods math against a throwaway
combatant, folds the marginal effect into the session, and re-applies
the persistent stat deltas onto the rebuilt player each round. Pure-
utility spells diff to nothing and are refused before a slot is spent.

Turn-based Elite/Boss fights gain !cast and !consume as player-turn
actions, so casters and item-users make decisions per round instead of
pre-queuing a single effect. The command handler validates and resolves
the spell/item into a pre-rolled turnActionEffect; the engine just
applies the HP deltas and flows on into the enemy turn.
Scoped to effects that resolve within the casting round: damage, heal,
and control spells, plus heal/flat-damage consumables. Buff and utility
spells and buff-type consumables are refused without spending the
resource — they need cross-round stat persistence, a later sub-phase.

combat_session.go: CombatSession persistence layer mirroring the
dnd_expedition pattern — CRUD accessors, one-active-per-user enforcement,
and the timeout reaper (sweeps stale sessions to 'expired').
combat_turn_engine.go: the player_turn -> enemy_turn -> round_end -> over
state machine. advanceCombatSession seeds a deterministic per-(round,phase)
RNG, resolves one phase via the shared attack primitives, commits, and
persists. The deferred poison/status tick lands in round_end now that the
round-loop shape exists.
CombatStatuses persists only between-round monster-ability effects; the
reaper marks sessions 'expired' rather than auto-playing them — both gaps
depend on Combatant reconstruction, which lands with the command-wiring PR.
