Nuker's "range" setting is silently overwritten every tick in Uniform Cube mode

[hokindo9000]

Describe the bug

In Nuker.java's onTickPre() handler, the range setting is written to
(not just read) on every single game tick when Uniform Cube shape is
selected:

if (shape.get() == Shape.UniformCube) range.set((double) Math.round(range.get()));

This calls the setting's set() method (a mutation, likely triggering
change listeners / marking config dirty for saving) every tick, purely to
round the displayed value - even when the value hasn't actually changed
between ticks.

Impact:

• Unnecessary repeated writes to a setting every tick (20 times/sec) for
  as long as Nuker is active with Uniform Cube shape selected, instead of
  only rounding the value once when it's changed or shape is switched.
• If the setting system persists/marks-dirty on every .set() call
  (common pattern), this could cause unnecessary repeated config save
  triggers purely from Nuker being left on.
• If a user is actively dragging the range slider, this per-tick
  overwrite could fight with/snap the UI value unexpectedly mid-drag.

Steps to reproduce

1. Enable Nuker.
2. Set shape to "UniformCube".
3. Observe (e.g. via a settings-change listener/log, or by dragging the
   range slider while active) that the range value is being rewritten
   every tick rather than only when actually changed.
