- renames the main header file to mjrfilament.h.
- moves filament_util under a "support" folder.

When an mjpResourceProvider's open callback returns 0 (failure), MuJoCo does
not invoke the corresponding close callback. Previously, several resource
provider implementations allocated heap memory or system file handles before
encountering an error, failing to clean them up before returning 0. This change addresses these leaks across the codebase and clarifies the API contract.

Use the jump flood algorithm to render an outline around selected
objects. This requires using custom post-processing shaders and
render passes which is managed by a new "Outliner" class.

Drag-and-drop uploads go through Module.loadFile and never reached the prefetcher. This is a guard for future provider schemes (e.g., vfs) that shouldn't be passed to fetch().

- C++ Platform UX: Added a "Copy Camera" button to copy XML camera definitions to clipboard.
- C++ Platform UX: Extracted `SetSpeedIndex` and `GetExpectedLabelWidth` into reusable platform helpers.
- C++ Platform UX: Fixed combo box widths and removed auto-hide tab bar flag from dockspace.
- C++ Studio App: Deduplicated label width and speed index logic by adopting platform helpers.
- C++ Studio App: Updated the toolbar layout to use a 2-column table.
- Python Bindings: Added pybind definitions for `set_camera_index`, `set_speed_index`, and `camera_to_string`.
- Python Studio App: Aligned toolbar UI with C++ using a 2-column table and fixed immediate theme switching.
- Python Studio App: Added a Help menu displaying the MuJoCo version and Stats toggle.
- Python Events: Added `-`/`=` shortcuts for simulation speed and `Esc`/`[`/`]` shortcuts for camera selection.

The prefetcher asks mju_getXMLDependencies for the transitive asset
list, fetches every URL with Promise.all, and primes the bytes into the
WASM-side FetchCache. When the compiler runs, every resource it opens
is already in memory. Cold-load on a typical Menagerie model drops from
~9 s to ~2 s.
Support Ctrl+Option+Left Click Drag (maps to Ctrl+Alt+Left Click Drag in the application) to apply point force perturbations (translation) on the robot in the WebGL live viewer. This matches the Mac experience in the native MuJoCo simulate app and provides a fallback for Mac users where Right Click is difficult to trigger.

Combines the "Solver" and "Performance" chart windows into a single "Profiler" window for better ergonomics and visual layout:
- Unified Dashboard: Groups the Solver block (Counts & Convergence) and the Performance block (Dimensions & CPU Time) in a single viewable window that scales cleanly without vertical scrollbars.
- Adaptive Stacking: Uses ImGui grouping so each block internally stacks its charts vertically, but tiles side-by-side horizontally when the window is stretched wide.
- Default Docking & Width: Integrates the Profiler into the default dockspace layout attached to the right of the main viewable area, with an optimized initial width scaling factor of 0.42.
- Shortcut and Menus: Adds a toggle shortcut bound to `F3`, updates the Help Shortcuts overlay, and replaces old separate entries in the Charts menu.

- Remove hard-coded button sizes (48×32) from toolbar icons; buttons now use default ImGui sizing, matching the existing copy-camera button.
- Remove the Unload button (available via menu).
- Add ImGui_ColorButtonEx widget with per-corner rounding via ImDrawFlags, enabling segmented button-group visuals.
- Use segmented rounding for the pause/viscous/play triplet: rounded-left, square, rounded-right.
- Make pause and play buttons 40% wider than the viscous button for emphasis.
- Replace the theme combo dropdown with a cycling button.
- Reduce toolbar height from 48px to 34px and vertically center content via WindowPadding.
- Zero out table CellPadding in the toolbar for precise vertical centering.
- Remove the speed combo's inflated vertical padding.

* **Dynamic Full-Window Scaling**: Charts in the Performance and Solver panels now expand to fill the entire pane, automatically arranging side-by-side or stacked based on window orientation to eliminate scrollbars.
* **Responsive Decorators**: Added reusable C++ ImPlot helper functions that auto-hide titles, legends, and tick labels when the plot surface is small.
* **Cleaner Visualization**: Refined chart titles (e.g., "CPU msec vs frame", "Convergence vs iter") and removed redundant axis labels for improved scannability.
These changes were based on the plot behavior of //third_party/mujoco/src/experimental/py/sample/implot.py This is an incremental improvement, we can make the plots even nicer in future.

- Reorder Physics section, move Actuator Groups to end.
- Rename "Physics Settings" → "Physics", "Rendering Settings" → "Rendering".
- Reduce IndentSpacing from 20 to 6.
- Reduce FramePadding Y from 6 to 2 for narrower buttons and popups.
- Remove explicit Unindent/Indent overrides in Rendering and Visibility Groups
sections so buttons are naturally indented under their tree nodes.
- Dynamically adjust convergence and counts plot X-axis limits based on actual
solver iterations instead of hardcoded 20.

This is a combination of minor tweaks to the existing Studio WASM application, CMake cleanup to make it buildable, and integration with GitHub Actions for deployment.
The new features added are drag-and-drop, model specification through `?model=` URL parameter, HTTP and HTTPS resource provider, and a user-visible loading message while the model is loading.

model_holder.cc modified to disable multi-threaded compilation for WASM builds. index.html `animate()` function modified so the animation rendering loop executes asynchronously with async/await calls. These changes are sufficient to make xml files without references work (e.g., humanoid.xml), more work is needed to make the vfs work so multi-file models can load.
