GameFeatureActions

CrimsonCore provides a full set of UGameFeatureAction subclasses that compose any feature into an experience via data assets. All GFAs are reversible — they undo their changes when the experience deactivates or the feature plugin is unloaded.

GFA class	What it does
`UGFA_AddAbilities`	Grants `UCrimsonAbilitySet`s (abilities + attribute sets + effects) to actors matching a class filter. Revokes on deactivate.
`UGFA_AddInputBinding`	Registers `UCrimsonInputConfig`s with `UCrimsonHeroComponent` on each player pawn. Removes bindings on deactivate.
`UGFA_AddWidget`	Pushes HUD layouts and registers widget extensions via `UIExtensionSubsystem`. Removes them on deactivate.
`UGFA_AddTeams`	Attaches `UCrimsonTeamAgentComponent` and populates team / hostile tags. Tears down on deactivate.
`UGFA_AddInventory`	Attaches `UCrimsonInventoryManagerComponent` with constraint and currency tables.
`UGFA_AddEquipmentSlots`	Attaches `UCrimsonEquipmentSlotsComponent` and `UCrimsonEquipmentManagerComponent` with a configured slot layout.
`UGFA_AddHotbar`	Attaches `UCrimsonHotbarContainerComponent` and per-hotbar manager components.
`UGFA_AddNPCSpawner`	Primes `UCrimsonEnemySpawnerSubsystem` before spawner actors tick.
`UGFA_AddSummons`	Enables summon ability support for the experience.
`UGFA_AddCompanions`	Enables companion roster on the PlayerState.
`UGFA_AddContainerInstances`	Registers `UCrimsonContainerData` payloads at a HUD extension slot.
`UGFA_SetupCamera`	Per-feature camera setup: assigns a UCrimsonLockOnConfig to the pawn's lock-on component (adds it if missing), optionally adds a lockable target component, and optionally overrides the pawn's default camera mode. Composes with existing components and restores all on deactivate.
`UGFA_SplitscreenConfig`	Reference-counted vote to disable splitscreen for the active world.
`UCrimsonGameFeatureAction_AddGameplayCuePath`	Registers gameplay cue notify paths with `UAbilitySystemGlobals` when the feature registers (not just when it activates).
