- Added selection behavior None (not selectable)
- Added selection behavior TryEnterState (enters the specific state, does not consider child states)
- Added selection behavior TryFollowTransitions (follows transitions when state is tried to be selected)
- Brushed up a bit the state representation in editor (added icons, cleaned up layout)

Initial version of the debugger
- currently compiled by StateTreeModule and StateTreeEditorModule using WITH_STATETREE_DEBUGGER
- currently not exposed to UI by StateTree settings 'bUseDebugger'
- in this version only one instance per asset can be debugged
- using Trace services to read events generated by statetree instances.
- can connect to any traces (Editor, Client, Server) as long as the compiled statetree matches

- Added ability for tasks to request transitions
- Added buffered transition requests
- Added callback method to FStateTreeTaskBase which is called during transition triggering
- Allow FStateTreeStateLink to be added to tasks and conditions (resolved automatically during compile)

- Calling GetStateTreeRunStatus() on unintialized instance is not error anymore, returns failed
- Made UStateTreeComponent::GetStateTreeRunStatus() to return failed instead of unset to be consistent with FStateTreeExecutionContext
- Allow to access execution state directly from instance data without exec context
- Do no crete exec context in UStateTreeComponent when sending events

[CL 23661828 by mikko mononen in ue5-main branch]
- Added global tasks which are run at tree level similar to evals (will replace evals)
- allows initial state selection to rely in calculated data (e.g. world conditions)
- allows better reuse of existing logic
- Call evaluator stop in reverse order
- Use some uses of mutable instanced structs
- Copy bindings along with ST nodes
- Remove bindings when removing a ST node, so that undo can restore them

- Removed gated delay (transition will be delayed until it has been "pressed" for N seconds)
- Delay now triggers after the delay duration has passed (single trigger, not "pressed", works with events too)
- Added random variation for the delay
- Tick/Event transitions has precedence over completion transitions (that is, they are handled before completion transitions)
- Removed delay and blocking from completion transitions
- Small improvements for transitions UI

- Use hierarchical GamplayTag match when matchin transition event tags
- When returning succeed/failed fomr a subtree, handle it as if the linked state was completed
- Call Stop() before initializing the instance data on Start() to avoid the instance data to be overritten by Stop()
- Early out Stop() if the tree is not running
- Fixed failed transition not setting OutTransition.CurrentActiveStates correctly

- Moved event queue to it's own struct
- Changed the SendEvent() API to accept struct view to prevent instanced struct copy in common cases
- Fixed event handling in case EnterState() fails.
- Added option for Tasks to disavble ticking, or to be ticked only when there are events
- Added option for Tasks handle when properties are copied
- Changed DebugText to use external Actor reference
- Changed DelayTask to use the new GetInstanceData which does not need type
- Added TStateTreeInstanceDataStructRef which can be used to access struct instance data in delegates

- Changed FStateTreeHandle to FStateTreeStateHandle, used only for indexing states
- Added uint16 and uin8 index types, which can represent invalid index (aka INDEX_NONE)
- Changed indices that can be optional to the index types above
- Added validation and error loggic when index types overflow during compile
