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 `clearSubtree` to recursively reset status for an entity and
all its descendants. This ensures that when a task reaches a terminal
state, its entire branch is properly reset.
Also refactor the Tetris example to use a sequential task node within
the behavior tree.
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).
