🔧 Add GLSL linting and formatting configuration

Add comprehensive GLSL development tooling with linting and formatting

- Add .glslrc.json configuration with WebGL compatibility settings
- Include GLSL extensions and version 4.6 core profile support
- Configure warnings for unused variables, functions, and deprecated features
- Add prettier-plugin-glsl to .prettierrc for GLSL code formatting
- Install GLSL tooling dependencies: glslang-validator, glslify, prettier-
plugin-glsl
- Add scripts/glsl-lint.js with comprehensive GLSL validation:
  * Extract and validate GLSL from TypeScript template literals
  * Check WebGL compatibility and deprecated function usage
  * Validate syntax, precision qualifiers, and main functions
  * Detect performance issues like nested loops and division by zero
  * Provide detailed error reporting with line numbers
- Add npm scripts for GLSL formatting and linting:
  * format:glsl and format:glsl:check for code formatting
  * lint:glsl and lint:glsl:fix for validation and auto-fixing
- Integrate GLSL checks into prepare-release workflow
- Add VS Code extension recommendations for GLSL development
