/** Global registry for Controllers to receive entity state updates.
|
||
*
|
||
* This singleton registry allows Controllers (APIServer, WebServer) to receive
|
||
* entity state change notifications without storing per-entity callbacks.
|
||
*
|
||
* Instead of each entity maintaining controller callbacks (32 bytes overhead per entity),
|
||
* entities call ControllerRegistry::notify_*_update() which iterates the small list
|
||
* of registered controllers (typically 2: API and WebServer).
|
||
*
|
||
* Controllers read state directly from entities using existing accessors (obj->state, etc.)
|
||
* rather than receiving it as callback parameters that were being ignored anyway.
|
||
*
|
||
* Memory savings: 32 bytes per entity (2 controllers × 16 bytes std::function overhead)
|
||
* Typical config (25 entities): ~780 bytes saved
|
||
* Large config (80 entities): ~2,540 bytes saved
