- Add core/compat.py: compatibility module with try/except imports
supporting both IS 4.x (omni.isaac.*) and IS 5.x+ (isaacsim.*)
- Migrate 152 imports across 47 files from direct omni.isaac.* to core.compat
- Handle class renames: RigidPrim→SingleRigidPrim, GeometryPrim→SingleGeometryPrim,
XFormPrim→SingleXFormPrim, Articulation→SingleArticulation (aliased for compatibility)
- Add migerate/migrate_imports.py: automated migration script for future use
- Leave debug_draw and env_loader try/except imports as-is
This eliminates ~100 deprecation warnings from our code on IS 5.0,
and future-proofs for IS 6.x when old APIs may be removed.

Camera.__init__() internally calls UsdGeom.Camera.Define() which
resets aperture to defaults, making it impossible to pre-set values.
The aperture mismatch warnings are cosmetic — IS auto-corrects them
and our values are applied correctly after init.

Camera.__init__() checks aperture consistency against resolution
before we can call set_horizontal_aperture(). Pre-set the aperture
values directly on the USD prim via UsdGeom.Camera API to eliminate
the mismatch warnings.
