The editor panel allows you to add, remove, and modify spec elements
as well as recompiling and loading the spec.
Also includes utilities for handling vertically split panels.

- Simplified constraint tree discovery with a unified iterator.
- Filling in a new `efc_tree` array to avoid calling tree discovery again in the constraint phase.
- Implemented dof skipping in the dense case for efficiency.

There are enough differences between how the two are structured that
having separate implementations makes things easier to implement
despite some minor code duplication.

This change updates the Emscripten build to output files named `mujoco.js`, `mujoco.wasm`, and `mujoco.d.ts` instead of `mujoco_wasm.*`. The internal CMake target name remains `mujoco_wasm` to avoid conflicts. The package name in `package.json` is also updated to `mujoco`. New enum tests are added.

Rename stubs.cc to mjr_compat.cc. This library acts like a
"compatibility layer" that allows the filament renderer to
be implemented behind the mjr API.

The `mjCOctree::ComputeSdfCoeffs` function has been replaced by `mjCOctree::ComputeSdf`. The new implementation removes the dependency on the `triangle_mesh_distance` library. Instead, it uses a provided `mjCBoundingVolumeHierarchy` to perform closest point queries on the mesh. The signed distance is computed by finding the closest triangle face via the BVH and determining the sign based on the dot product of the vector from the closest point on the triangle to the octree vertex and the triangle's normal.
Optional Laplacian smoothing has been added to the SDF coefficients. This helps smooth out potential discontinuities at octree level boundaries.

This change introduces methods to cache and load the computed stiffness matrix and nodal masses for flex elements. The cache key is generated based on material properties (Young's modulus, Poisson's ratio), interpolation order, and the bounding box of the flex. This avoids redundant expensive computations when compiling models with identical flex definitions.

The logic for computing Signed Distance Function (SDF) coefficients using TriangleMeshDistance is moved from `mjCPlugin::Make` in `user_mesh.cc` to a new method `mjCOctree::ComputeSdfCoeffs` in `user_objects.cc`. This encapsulates the SDF computation within the octree class.

MujocoTest now loads plugins from MUJOCO_PLUGIN_DIR if set.
PluginTest is removed; all tests use MujocoTest directly.
testspeed binary loads plugins from MUJOCO_PLUGIN_DIR.
This is in preparation for moving common asset format parsing (obj, msh, stl, etc.) where we will always want to load those plugins.

The reduced dense factorization for flex interpolation now considers all DOFs in the kinematic chain of the body containing the flex, using mj_bodyChain, instead of only the DOFs directly associated with that body. This is necessary for correctly handling pinned flexes when their parent body is part of a larger kinematic structure.
