Rework task execution to be synchronous within a single tick.
Scheduling boundaries are now defined by `cycle` nodes, which
replace the previous `repeat` decorator. All tasks are executed
immediately when scheduled, and parent/child propagation is
handled inline.
The `LegacyTreeDef` type and its normalization path have been removed.
All tree definitions must now use the factory functions (`leaf`,
`sequential`, `parallel`, `selector`, `random`, `repeat`). The
`TreeDef` type is now simply `TaskEntityDef`.
Add `leaf`, `sequential`, `parallel`, `selector`, `random`, and `repeat`
functions that return `EntityDef` trees. Legacy object definitions are
still
accepted for backward compatibility. Non-task child entities are ignored
by
the runner, and `buildTree` now stores the root entity on
`TaskRunner.root`.
Introduce support for generator functions in leaf tasks, allowing
them to yield for multi-frame execution. The `TaskRunner` now accepts
a delta time (`dt`) parameter, which is passed through to leaf
handlers.
Additionally, a `Cancel` symbol is introduced to allow leaf tasks to
explicitly cancel their subtree via a thrown error.
Introduce `buildTree` to allow defining behaviour trees using a
declarative `TreeDef` object instead of manual entity spawning and
relationship wiring. This simplifies tree construction and manages
leaf handlers internally.
Introduces a `TaskRunner` for executing behavior trees within the
ECS world. Supports leaf, sequential, parallel, and random task
kinds, along with status propagation (succeeded, failed, cancelled).
