Add first-class Vite frontend scaffolding for React, Vue, Svelte, and Tailwind

[techmahedy]

This PR adds first-class frontend scaffolding to Doppar with:

• php pool frontend:install --force (passing force will override existing app and welcome files)
• php pool frontend:uninstall
• native Vite runtime support through vite()
• resources/client as the frontend source directory
• React/Vue/Svelte/Vanilla setup support
• Tailwind and Bootstrap setup options
• production fallback to public/build

What To Test

Please verify:

• the install command works interactively
• generated files are correct
• dev mode works with npm run dev
• production build works with npm run build
• Tailwind classes compile correctly
• vite() falls back to built assets when the dev server is stopped
• uninstall removes the scaffold cleanly

Fresh Install Flow

Start from the project root:

php pool frontend:install

This will start like this way:

The layout should contain a Vite call similar to:

#vite('resources/client/js/main.tsx')

or the raw helper form if you are testing directly:

[[! vite('resources/client/js/main.tsx') !]]

Dev Mode Test

Start Doppar:

php pool server:start

Start Vite:

npm run dev

Open the app in the browser:

http://localhost:8000

Expected result:

• the client frontend should render
• page navigation should work
• styles should be visible

Build the frontend:

npm run build

Uninstall Test

Run:

php pool frontend:uninstall

Optional:

php pool frontend:uninstall --clean-node-modules

Expected result:

• scaffolded frontend files should be removed or restored from backup
• resources/client should be cleaned up if it did not exist before install
• public/build should be removed when owned by the scaffold lifecycle
• layout patches should be removed

Suggested Reviewer Path

For the fastest review:

1. Run php pool frontend:install
2. Start php pool server:start
3. Start npm run dev
4. Visit /,
5. Stop Vite
6. Run npm run build
7. Reload /
8. Run php pool frontend:uninstall

If all of the above works, this PR is behaving as intended.
