Moves ~300 lines of test simulation logic (Bresenham LOS, collision,
procedural room generation, movement physics, dialogue triggers) from
the production sim_bridge.gd autoload into a dedicated TestHarness
class at scripts/protocol/test_harness.gd. Enforces D-020 information
boundary — no game logic in the production client.
SimBridge retains thin proxy properties and methods for backward
compatibility with 13+ test files (zero test changes needed).
