Adding an object to the game no longer requires any networking code. The
MultiplayerSpawner runs in its default mode — no spawn_function, no payload
dictionary — and NetReplication builds each object's SceneReplicationConfig
from a convention, so scenes carry no hand-authored replication at all.
Every replicated node gets two generated synchronizers: NetSync for script
state, always server-owned, and NetXform for position, handed to whoever is
holding the object. That split is what makes grab prediction work — a
synchronizer never applies inbound state on the peer that owns it, so a
player's own hand drives an object with no round trip while is_dirty and
friends keep flowing one way from the server.
Interaction is now two RPCs for the whole game (NetGrab), and client gating is
one rule applied to every object (NetWorld). Deleted: net_pickable.gd, the
replicated net_held_by field and its held-state juggling, the
grant/reject/force-release negotiation, the static-item despawn RPC, and the
per-scene replication configs. Authority is the single source of truth for who
simulates an object.
Two things the convention had to learn, both found by the test suite:
* Addon scripts are excluded. godot-xr-tools' snap zones and pickables expose
a public `enabled`, which is exactly the flag each peer must set for itself
— so replicating it meant the server sent `enabled = true` back over every
client's gate, and stations went on grabbing objects out of the local
player's hands.
* Arrays of nodes are excluded. Array[Node3D] and Array[FoodItem] would
otherwise try to serialise live node references.
table.gd's replicated state loses its underscore prefix, which now marks a
variable as private and unreplicated; two in-place array mutations there were
skipping their setters, and the progress bar could divide by zero on a client.
Suite: 146/146 passing.

The world was populated before NetworkManager.world_ready() actually
called host()/join(), so owns_world() read true for every peer
(including a joining client) and each one built its own local,
unreplicated copy instead of the client receiving the server's spawn
through the MultiplayerSpawner. Population now happens after the
session is actually established.
Also adds net-log coverage for spawn/despawn, station gating, item
authority handoff, station snapping, avatar spawn/despawn, and scene
transitions, so multiplayer behavior is visible in
%TEMP%\vryhungry_net_<pid>.log instead of failing silently.
