Release: Refactor Load Types (#2241)

A very common source of annoyance and confusion is that trimesh.load
can return lots of different types depending on what type of file was
passed (i.e. #2239). This refactor changes the return types for the
loading functions to:

• trimesh.load_scene -> Scene
• This loads into a Scene, the most general container which can hold
  any loadable type. Most people should probably use this to load
  geometry.
• trimesh.load_mesh -> Trimesh
• Forces all mesh objects in a scene into a single Trimesh object.
  This potentially has to drop information and irreversibly concatenate
  multiple meshes.
• The implementation of the concatenation logic is now in
  Scene.to_mesh rather than load.
• trimesh.load_path -> Path
• This loads into either a Path2D or Path3D which both inherit from
  Path
• trimesh.load -> Geometry
• This was the original load entry point and is deprecated, but there
  are no current plans to remove it. It has been modified into a thin
  wrapper for load_scene that attempts to match the behavior of the
  previous loader for backwards compatibility. In my testing against the
  current main branch it was returning the same types 99.8% of the
  time
  although there may be other subtle differences.
• trimesh.load(..., force='mesh') will emit a deprecation warning in
  favor of load_mesh
• trimesh.load(..., force='scene') will emit a deprecation warning in
  favor of load_scene

Additional changes:

• Removes Geometry.metadata['file_path'] in favor of
  Geometry.source.file_path. Everything that inherits from Geometry
  should now have a .source attribute which is a typed dataclass. This
  was something of a struggle as file_path was populated into metadata
  on load, but we also try to make sure metadata is preserved through
  round-trips if at all possible. And so the load inserted different
  keys into the metadata. Making it first-class information rather than a
  loose key seems like an improvement, but users will have to replace
  mesh.metadata["file_name"] with mesh.source.file_name.
• Moves all network fetching into WebResolver so it can be more easily
  gated by allow_remote.
• Removes code for the following deprecations:
• January 2025 deprecation for trimesh.resources.get in favor of the
  typed alternatives (get_json, get_bytes, etc).
• January 2025 deprecation for Scene.deduplicated in favor of a very
  short list comprehension on Scene.duplicate_nodes
• March 2024 deprecation for trimesh.graph.smoothed in favor of
  trimesh.graph.smooth_shaded.
• Adds the following new deprecations:
• January 2026 Path3D.to_planar -> Path3D.to_2D to be consistent
  with Path2D.to_3D.
