refactor(client): extract SnapshotEventRouter from main.gd (#559)

Browse Source 
New SnapshotEventRouter class (46 lines) provides callable-based
snapshot dispatch via register(), register_always(), and dispatch().
main.gd _process() now calls _router.dispatch(snapshot) instead of
15+ inline if-has blocks. Handlers registered in _ready().

class_name SnapshotEventRouter
## Routes snapshot fields to registered handlers (D-020, #559).
##
## Decouples main.gd from knowing which child node handles which snapshot field.
## Handlers are registered in main.gd._ready(); dispatch() is called each snapshot tick.
##
## Two handler types:
## - Keyed: called only when the snapshot contains a specific field.
## - Always: called every dispatch (every snapshot tick), regardless of fields present.
##
## All handlers are zero-argument callables — they read from GameState directly.
## This preserves GameState as the single source of truth post-apply_snapshot().
## Keyed handlers: field_name → Array[Callable]
## Array per field allows multiple handlers on the same key (e.g., two consumers of same data).
var _keyed: Dictionary = {} # String → Array[Callable]
## Always handlers: called every dispatch regardless of snapshot content.
var _always: Array[Callable] = []
## Register a handler for a specific snapshot field key.
## Handler is called (with no arguments) when snapshot.has(field) is true.
## Multiple handlers per field are supported — they run in registration order.
func register(field: String, handler: Callable) -> void:
if not _keyed.has(field):
_keyed[field] = []
_keyed[field].append(handler)
## Register a handler that runs every dispatch tick (not keyed to a field).
## Use for child nodes that update from GameState on every snapshot, e.g. update_from_state().
func register_always(handler: Callable) -> void:
_always.append(handler)
## Dispatch a snapshot: call always handlers first, then keyed handlers for present fields.
## Handlers read from GameState.* directly — apply_snapshot() must be called before dispatch().
