## Summary
* **Why change is necessary?** New feature - adds MicroQuickJS JavaScript
interpreter support to NuttX
* **What functional part of the code is being changed?** New interpreter
module added in `interpreters/mquickjs/` directory.
* **How does the change exactly work?**
- FetchContent automatically downloads mquickjs source from
bellard/mquickjs if not present locally
- Builds mqjs_stdlib host tool to generate required headers
(mqjs_stdlib.h, mquickjs_atom.h) during build
- Creates libmquickjs library with proper dependency handling for
parallel builds
- Provides mqjs NSH command for interactive JavaScript execution
- Supports both CMake and Make build systems
## Impact

integration
* **Impact on user?** YES - Users can now enable and use JavaScript
interpreter by enabling `CONFIG_INTERPRETERS_MQJS` in Kconfig
* **Impact on build?** YES - Adds new build target and configuration option
* **Impact on hardware?** NO - Works across architectures (32-bit and
64-bit)
* **Impact on documentation?** YES - Documentation should be added in
nuttx repository (separate PR)
* **Impact on security?** NO - Standard JavaScript interpreter integration
* **Impact on compatibility?** NO - Pure addition, no breaking changes
