feat(render-core): add default UV scale and refactor UV mapping logic

- Introduced a constant `DEFAULT_UV_SCALE` for UV scaling.
- Refactored UV mapping in `build_render_mesh` to use the new constant.
- Simplified `compute_bounds` functions by extracting common logic into `compute_bounds_impl`.

test(render-core): add tests for rendering with empty and multi-node models

- Added tests to verify behavior when building render meshes from models with no slots and multiple nodes.
- Ensured UV scaling is correctly applied in tests.

feat(render-demo): add FOV argument and improve error handling

- Added a `--fov` command-line argument to set the field of view.
- Enhanced error messages for texture resolution failures.
- Updated MVP computation to use the new FOV parameter.

fix(rsli): improve error handling in LZH decompression

- Added checks to prevent out-of-bounds access in LZH decoding logic.

refactor(texm): streamline texture parsing and decoding tests

- Created a helper function `build_texm_payload` for constructing test payloads.
- Added tests for various texture formats including RGB565, RGB556, ARGB4444, and Luminance Alpha.
- Improved error handling for invalid TEXM headers and mip bounds.
