- Add `_syncEscortSpeed()` in GameScene: when an escort contract is open, the transport is on screen, and combat is inactive, cap the player hull and escort fighters at the transport's own top speed; restore each craft to its normal/roster speed otherwise.
- Fighters keep their base speed on `_baseSpeed` so the restore is exact even after a jump re-form.
- Per-frame writes only on change to avoid steady-state churn or steering disturbance.
- Hook the sync into `updateSideQuestRoute()` so it runs each frame off the escort lane (no-op elsewhere).
- Cover the new behavior in `escort-flow.test.mjs`: match applies in view/out-of-combat, restores on combat open, transport off-screen, and contract end; give test crafts distinct speeds so match and restore are observable.
