The F1 overlay lists only the most common commands, and there was no
complete shortcut list anywhere in the docs. Add one to the simulate
section, derived from the shortcut declarations in simulate.cc,
simulate.h, mjVISSTRING and mjRNDSTRING.
Fixes#3306
Support named CLI flags, physics overrides, and refactor global state.
- **Named CLI Flags**: Replaced standard positional arguments with named flags (`--nstep`, `--nthread`, `--noisestd`, `--noiserate`, `--npoolthread`) and preserved Google-wide flags compatibility (via custom argv compacting and InitGoogle).
- **Physics Option Overrides**: Added support for configuring loaded model settings directly from the command line (`--solver`, `--cone`, `--jacobian`, `--integrator`, `--iterations`, `--tolerance`, `--sleep_tolerance`, `--noslip_iterations`).
- **Encapsulated Thread State**: Consolidated loose global variables and per-thread rollout statistics arrays into a single data structure, `RolloutRunner runner`, simplifying mutli-threaded data boundaries.
- **Readable Physics Options Printing**: Logged configured non-default options dynamically prior to rollout. Enums and active bitmask flags (e.g. disableflags/enableflags) are decoded into friendly strings (e.g., `Sleep : Enabled`).
- **Tests & Docs**: Added testspeed_test.sh running testspeed over dominos.xml to check all overrides, registered shell test target in BUILD and CMakeLists.txt, and updated samples.rst documentation.

For example when loading parent_merge.xml:
```
WARNING: Attach conflict when attaching 'child' to 'parent_merge', policy is 'merge'
timestep: parent has 0.005, child has 0.002, taking the minimum
iterations: parent has 50, child has 100, taking the maximum

```
When loading parent_error.xml:
```
XML Error: Attach conflict when attaching 'child' to 'parent_error', policy is 'error'
timestep: parent has 0.005, child has 0.002

Previously on MSVC we used DllMain to register plugins, you cannot have multiple definitions of DllMain in a single unit so you would get errors if you tried to register two plugins. This modifies the implementation to insert a function pointer into the C runtime initialization instead.

All known implementations were effectively the same as the default fallback. It was just adding unneeded complexity. Removing this now will help with upcoming improvements to resource providers.

The previous instructions use a pre-built binary from MuJoCo and do not cover
the use-case of building C/C++ and Python bindings from the same codebase.

Note that small videos, for some reason, need an aspect ratio that is different from the actual aspect ratio.

This enables to find the spec associated with the compiler option stored in the objects, which do not necessarily belong to the model that owns them.
