Feat: Integrate Inertia.js for frontend framework support

Background: Inertia.js allows us to create modern single-page React, Vue, and Svelte apps using classic server-side routing, for this reason we need to integrate Inertia to improve the DX and portability of the framework. This provides SPA-like behavior while keeping routing and controllers on the backend.

Tasks:

• Install and configure Inertia.js server-side adapter.
• Add your implementation to the framework/view package directory
• Provide middleware for sharing props globally to all Inertia responses.
• Add helpers to return Inertia responses from controllers.
• Ensure compatibility with Vue, React, and Svelte adapters on the frontend.
• Add sample demo showing controller → Inertia → frontend rendering.
• Write tests to ensure Inertia responses and shared props work correctly.

Acceptance criteria:

• Controllers can return inertia('Dashboard', { user }) and render correctly in chosen frontend.
• Global shared props are available across all Inertia pages.
• Works with multiple frontend adapters.
• Interface mirrors laravel as much as possible, creating the familiar DX while also adding it own unique twists and turns.
