Suppress compass nav chips during active combat

- While `this.combat.active` is true, call `compass.refresh([])` and
  return early so edge arrows and name boxes step aside.
- Combat chrome (threat markers, off-screen hostile arrows, kill feed)
  owns the screen edge while the player is shooting; nav chips would
  only compete with it.
- The target set is recomputed every frame, so nothing is lost — a
  mid-fight discovery still pings above, and the first non-combat frame
  re-feeds the compass entries.
