Enhance TypeScript configuration with recommended options

Problem

The tsconfig.json is missing several recommended compiler options for VSCode extensions.

Solution

Add the following enhancements to tsconfig.json:

{
    "compilerOptions": {
        "module": "Node16",
        "target": "ES2022",  // Bump from ES2019 to ES2022
        "lib": ["ES2022"],
        "outDir": "out",
        "sourceMap": true,
        "skipLibCheck": true,
        "moduleResolution": "Node16",
        "esModuleInterop": true,
        "strict": true,
        "noUnusedLocals": true,
        "noUnusedParameters": true,  // Enable this
        "noImplicitReturns": true,   // Enable this
        "noFallthroughCasesInSwitch": true,  // Enable this
        "forceConsistentCasingInFileNames": true,  // Add this
        "resolveJsonModule": true,  // Add this for JSON imports
        "declaration": true,  // Generate .d.ts files
        "declarationMap": true  // Generate declaration source maps
    },
    "include": ["src/**/*", "test/**/*"],
    "exclude": ["node_modules", ".vscode-test", "out", "dist"]
}

Also add to package.json:

{
  "type": "commonjs",
  "engines": {
    "node": ">=18.0.0"
  }
}

Why These Matter

• target: ES2022: VSCode engine supports modern JavaScript
• noUnusedParameters: Prevents unused function parameters
• noImplicitReturns: Ensures all code paths return values
• forceConsistentCasingInFileNames: Prevents cross-platform issues
• resolveJsonModule: Allows importing package.json for metadata
