visual_capture.gd runs via `godot -s`, where the `class_name` registry isn't
populated — so the bare `Protocol.decode_snapshot()` reference failed to
compile, breaking ALL --screenshot/--movie/golden captures (not just the
replay scenarios that use it). Instantiate the script and call the static
decoder on the instance (then free), matching the file's existing -s-mode
load() workaround for VisualScenarios.

Add live server lifecycle to tests/run-visual (start/stop server per
scenario, parse LISTENING:{port}). Add MessagePack snapshot replay to
visual_capture.gd via Protocol.decode_snapshot() — exercises the full
client pipeline from wire bytes to rendered fog. Three replay scenarios
(hub_spawn, fog_theater, hub_after_movement) plus one live scenario
(fog_live_hub). Add gen_gauntlet_fixtures.rs to produce .msgpack fixtures
from the Gauntlet test world. Add max_diff_pct threshold to visual-diff.
Makefile: add fixtures-gauntlet target, fix build-client double-import,
preserve .godot cache in clean.
