docs: enhance TypeScript standards and remove type suppressions

Strengthens code quality guidelines by establishing strict TypeScript practices that prohibit `any` types and minimize type suppressions.

Updates Copilot instructions to emphasize production-ready code with comprehensive type safety rules, error handling requirements, and reliability standards. Explicitly discourages type escape hatches in favor of proper type definitions.

Refactors navigation implementation to use URLSearchParams instead of object-based params, eliminating the need for type suppression while maintaining functionality.

Removes unnecessary type error suppressions and unused properties throughout codebase, aligning with new standards.

+**CRITICAL: Code must be production-ready, reliable, and maintainable**
+
+### Type Safety
 - Use TypeScript for ALL files (no .js files)
+- **NEVER use `any` type** - use proper types, generics, or `unknown` with type guards
+- Use `@ts-expect-error` with detailed comments only when necessary (e.g., library limitations)
+- When facing type issues, create proper type definitions and helper functions instead of using `any`
+- Use type assertions (`as`) only as a last resort with clear documentation explaining why
+- For Expo Router navigation: prefer string URLs with `URLSearchParams` over object syntax to avoid type conflicts
+- Enable and respect strict TypeScript compiler options
+- Define explicit return types for functions
+- Use discriminated unions for complex state
+
+### Code Reliability
+- Implement comprehensive error handling with try-catch blocks
+- Validate all external inputs (API responses, user input, query params)
+- Handle edge cases explicitly (empty arrays, null, undefined)
+- Use optional chaining (`?.`) and nullish coalescing (`??`) appropriately
+- Add runtime checks for critical operations
+- Implement proper loading and error states in components
+
+### Best Practices
 - Use descriptive English names for variables, functions, and components
 - Prefer functional React components with hooks
 - Use Jotai atoms for global state management
