Add optional apparel sync (equippedItems)

Introduce an optional equippedItems transform extension to snapshot tracked visible apparel slots. Plugin: capture local equipped ARMO form IDs on the game-thread, include equippedItems in transform packets, parse equippedItems on the networking thread, and apply/clear synced apparel on runtime proxies (with defensive logging for missing forms). Server: fake_client parses and prints equippedItems. Docs and protocol updated; changelog and dev-log entry added. Backwards-compatible: equippedItems is optional and empty formId denotes intentional unequip.
