 Components for match rule tracking.

 

 ## Components

 

 | Component | Description |

 |-----------|-------------|

 | `PlayerComponent` | Marker identifying the player entity |

 | `LivesComponent` | Tracks remaining lives with revision-based change detection |

 | `LivesBindingComponent` | Binds a UI entity to a target's LivesComponent |

 

 ## LivesComponent

 

 Maintains a life counter and a monotonically increasing `LivesRevision`.

 Each call to `decrease()` or `increase()` bumps the revision so observer

 systems can detect changes without polling.

 

 ## LivesBindingComponent

 

 Stores a target `EntityHandle` and a cached `LivesRevision`. The

 `Lives2UiTextUpdateSystem` compares the cached revision against the

 target's current revision to update the bound UI text on change.

 

 ## PlayerComponent

 

 Empty marker component. Systems query for it to apply player-specific

 logic (input handling, camera, UI).
