chore(deps): update TypeSpec and ESLint dependencies to latest stable versions

## Summary

Updated multiple npm dependencies in package.json to their latest stable
versions, ensuring the project stays current with upstream libraries and
receives the latest bug fixes, performance improvements, and security
patches.

## Changes Made

### Dev Dependencies Updated
- @typescript-eslint/eslint-plugin: ^8.59.3 → ^8.61.0
- @typescript-eslint/parser: ^8.59.3 → ^8.61.0
- @typespec/compiler: 1.12.0 → 1.13.0
- @typespec/http: 1.12.0 → 1.13.0
- eslint: ^10.4.0 → ^10.4.1
- prettier: ^3.8.3 → ^3.8.4

### Peer Dependencies Updated
- @typespec/compiler: 1.12.0 → 1.13.0 (aligned with dev dependency)
- @typespec/http: 1.12.0 → 1.13.0 (aligned with dev dependency)

## Rationale

1. **TypeSpec 1.13.0**: Major version bump in the TypeSpec compiler and http
   package brings new language features, improved type checking, and updated
   API surface that may be required by downstream TypeSpec Go emitters.

2. **ESLint 8.61.0**: Updated TypeScript ESLint packages provide better
   TypeScript 6.x compatibility, improved rule performance, and additional
   linting capabilities for stricter code quality enforcement.

3. **Prettier 3.8.4**: Latest patch release includes bug fixes and minor
   improvements to code formatting consistency.

4. **ESLint 10.4.1**: Minor patch update with bug fixes for ESLint 10.x

## Impact

- Low risk: patch and minor version updates with backward-compatible changes
- Both devDependencies and peerDependencies updated in sync for consistency
- No breaking changes expected for existing TypeSpec Go emitter functionality
