Owner

The test that proves M1's architecture holds: a full mission, resolved headlessly, with
no rendering and no window.

If this test is hard to write, the simulation/presentation split is wrong, and that is
the finding — fix the split rather than the test.

Scope

Build a minimal App with MinimalPlugins, StatesPlugin, and only the combat,
world, and character plugins — in the style of the headless() helper in
src/core/state.rs and the roster test in src/character/mod.rs.
Drive a scripted sequence of actions from a fixed seed to a known victory.
Replay the identical sequence and seed, asserting an identical outcome — final
positions, health, and the full event log.

Acceptance criteria

The test runs with no rendering plugins and no display.
Determinism is asserted on the whole event log, not just the winner.
The test completes fast enough to stay in the default cargo test run.
Running the same test twice in one process gives the same result — no leaked
global state between missions.
