refactor: consolidate type system and improve documentation

- Move type definitions from src/types/ to src/interfaces/ for better organization
- Enhance deep linking type system documentation with detailed examples
- Update package dependencies to latest versions
- Improve code organization in README.md
- Fix formatting in WebPlatformService.ts

This change consolidates all type definitions into the interfaces folder,
improves type safety documentation, and updates dependencies for better
maintainability. The deep linking system now has clearer documentation
about its type system and validation approach.

Breaking: Removes src/types/ directory in favor of src/interfaces/

doc/DEEP_LINKS.md

    - Enforces parameter requirements
    - Sanitizes input data
    - Provides detailed validation errors
+   - Generates TypeScript types automatically
 
 2. **TypeScript Types**
-   - Generated from Zod schemas
+   - Generated from Zod schemas using `z.infer`
    - Ensures compile-time type safety
    - Provides IDE autocompletion
    - Catches type errors during development
+   - Maintains single source of truth for types
 
 3. **Router Integration**
    - Type-safe parameter passing
    - Route-specific parameter validation
    - Query parameter type checking
+   - Automatic type inference for route parameters
+
+## Type System Implementation
+
+### Zod Schema to TypeScript Type Generation
+
+```typescript
+// Define the schema
+const claimSchema = z.object({
+  id: z.string(),
+  view: z.enum(["details", "certificate", "raw"]).optional()
+});
+
+// TypeScript type is automatically generated
+type ClaimParams = z.infer<typeof claimSchema>;
+// Equivalent to:
+// type ClaimParams = {
+//   id: string;
+//   view?: "details" | "certificate" | "raw";
+// }
+```
+
+### Type Safety Layers
+
+1. **Schema Definition**
+   ```typescript
+   // src/interfaces/deepLinks.ts
+   export const deepLinkSchemas = {
+     claim: z.object({
+       id: z.string(),
+       view: z.enum(["details", "certificate", "raw"]).optional()
+     }),
+     // Other route schemas...
+   };
+   ```
+
+2. **Type Generation**
+   ```typescript
+   // Types are automatically generated from schemas
+   export type DeepLinkParams = {
+     [K in keyof typeof deepLinkSchemas]: z.infer<(typeof deepLinkSchemas)[K]>;
+   };
+   ```
+
+3. **Runtime Validation**
+   ```typescript
+   // In DeepLinkHandler
+   const result = deepLinkSchemas.claim.safeParse(params);
+   if (!result.success) {
+     // Handle validation errors
+     console.error(result.error);
+   }
+   ```
+
+### Error Handling Types
+
+```typescript
+export interface DeepLinkError extends Error {
+  code: string;
+  details?: unknown;
+}
+
+// Usage in error handling
+try {
+  await handler.handleDeepLink(url);
+} catch (error) {
+  if (error instanceof DeepLinkError) {
+    // Type-safe error handling
+    console.error(error.code, error.message);
+  }
+}
+```
