docs: add MeasurementTools example notebook

[Copilot]

Adds a documentation example demonstrating MeasurementTools usage, following the existing RepairTools example pattern and the contributing guide's example conventions.

Changes

• doc/source/examples/05_tools/measurement_tools.mystnb — New example notebook covering:
  • Measuring minimum distance between two Body objects
  • Measuring between Face objects (requires Ansys 25R2+)
  • Measuring between Edge objects (requires Ansys 25R2+)
• doc/source/examples.rst — Added entry in "Tools examples" gallery; updated section description to mention MeasurementTools
• doc/source/conf.py — Added thumbnail mapping for the new example
• doc/source/_static/thumbnails/measurement_tools.png — Placeholder thumbnail

Usage

from ansys.geometry.core import launch_modeler
from ansys.geometry.core.math import UNITVECTOR3D_X, Point2D
from ansys.geometry.core.misc import UNITS
from ansys.geometry.core.sketch import Sketch

modeler = launch_modeler()
design = modeler.create_design("MeasurementToolsDemo")

sketch1 = Sketch().box(Point2D([0, 0], unit=UNITS.m), width=1 * UNITS.m, height=1 * UNITS.m)
box1 = design.extrude_sketch("Box1", sketch1, 1 * UNITS.m)

sketch2 = Sketch().box(Point2D([0, 0], unit=UNITS.m), width=1 * UNITS.m, height=1 * UNITS.m)
box2 = design.extrude_sketch("Box2", sketch2, 1 * UNITS.m)
box2.translate(UNITVECTOR3D_X, 3)

gap = modeler.measurement_tools.min_distance_between_objects(box1, box2)
print(f"Minimum distance: {gap.distance}")

modeler.close()
