| sim_models: introduce scene compiler and pick_banana Gazebo scene
Add sim_models as an ament Python package providing scene assets and a
scene compiler API for simulation backends.
scene_compiler.py exposes 4 public functions:
- get_scene_file(name, platform): return template file path
- get_gazebo_world_path(name): generate /tmp/ world with absolute mesh URIs
- get_mujoco_scene_path(name, robot_xml_path): generate /tmp/ MJCF for MuJoCo
- get_scene_layout(name): return parsed layout.yaml dict
pick_banana scene includes bluetable, plate, banana and green curtain with 6
OBJ mesh assets reused from mujoco_ros2_control_so101. Coordinate system is
aligned with MuJoCo: ground_plane at z=-0.274 (visible floor), invisible
table_surface_collision plane at z=0 so dynamic objects settle on the table.
layout.yaml carries a robot_spawn field so the scene (not the robot config)
owns the per-scene spawn Z offset. GazeboAdapter.start_backend() reads
simulation.scene from the robot YAML, calls get_gazebo_world_path() to
obtain the resolved world file, and applies robot_spawn.{x,y,z} to
override initial_pose values before spawning the robot entity.
Enable pick_banana in so101_single_arm.yaml (previously null).

| feat(sim): align Gazebo/MuJoCo cameras, assets and lighting
Add camera_presets.py with platform-specific default camera poses so
that a single YAML config (use_default_transform: true) works for both
Gazebo and MuJoCo without manual coordinate conversion.
Update pick_banana Gazebo world template to match layout.yaml canonical
values (table scale 0.156, banana x=0, curtain yaw flip, ground z).
Tune MuJoCo lighting: reduce headlight diffuse, use single shadow-
casting directional light, add low-specular materials for table and
robot to eliminate top-camera overexposure.
Add Gazebo material overrides in so101_gazebo.xacro so the robot arm
renders with correct colors instead of default grey.
