feat(client): upgrade protocol decoder and GameState for v2 snapshot

Browse Source 
Server shipped ObserverSnapshot v2 with game_time, player_facing,
visible_tiles (with visibility sectors), and per-entity visibility.
Protocol decoder was silently ignoring these fields. Now extracts
all v2 data with null defaults for backward compatibility.

GameState gains game_time, player_facing, visibility_sectors vars.
Derives visible_positions from visible_tiles when present (for real
server mode). Test snapshot updated with v2 fields.
