🧹 Remove explicit any on window in Hero.astro

[kuasar-mknd]

🎯 What: The explicit window as any cast and its associated eslint-disable override have been removed from src/components/features/home/Hero.astro. To support type safety, __heroInitHandler has been properly declared on the global Window interface in src/env.d.ts.

💡 Why: Relying on any bypasses TypeScript checks and makes the code less robust to refactoring. By extending the built-in Window interface directly, we improve code health, ensure the listener's types are checked appropriately globally, and remove unnecessary eslint ignores.

✅ Verification:

• Modified src/env.d.ts and src/components/features/home/Hero.astro.
• Ran pnpm run check (formatter, linter, and type checker) locally. All passed successfully.
• Ran pnpm run build locally, completing without issues.
• Installed playwright deps and ran pnpm run test:e2e. All E2E tests passed.

✨ Result: A safer, more robust implementation without an explicit type override or linting ignore, adhering to the codebase's existing pattern of global interface augmentation.
