Cap atlas size to device max_texture_dimension_2d
...
RPi5 GPU limits max texture dimension to 2048, but atlas was hardcoded
to 2560. Now clamps to device.limits().max_texture_dimension_2d.

Use downlevel_limits for RPi5 compatibility
...
Limits::default() requests max_color_attachments=8, but RPi5 Vulkan
only supports 4. downlevel_defaults() uses 4, which is all we need.

Re-enable GPU backends for RPi5 and cross-platform support
...
Features now: std, spirv, parking_lot, vulkan, gles, metal, dx12
Drops wgsl (replaced by SPIR-V passthrough), keeps all platform backends.
.so size: 9.4 MB -> 4.0 MB

Reduce .so from 9.4 MB to 721 KB via SPIR-V passthrough and release optimizations
...
- Compile shader.wgsl to SPIR-V at build time, commit .spv to repo
- Use wgpu PASSTHROUGH_SHADERS feature to skip naga runtime
- Disable default wgpu features, keep only 'spirv'
- Add release profile: LTO, strip, opt-level=z, panic=abort, codegen-units=1
- Use create_shader_module_passthrough() instead of create_shader_module()
To regenerate shader.spv after editing shader.wgsl:
naga-cli src/shader.wgsl shader.spv
