feat: Add marko/vite package

[ps-carvalho]

Summary

This is PR 1/5 in the stacked package-import sequence for Marko Vite + Inertia packages.

Preceding dependency PR: none. This PR starts the stack from upstream/develop.

Adds marko/vite as a monorepo package under packages/vite, registers it in root Composer metadata, and imports the package tests without standalone package tooling files.

Maintainer Feedback Addressed

• Config-loading failures are loud through package exceptions instead of falling back silently.
• Standalone tooling files are not imported.
• Package-local Composer scripts and redundant tooling dev dependencies are removed.
• marko/env remains a runtime dependency because config/vite.php uses env().

Test Plan

• composer validate --strict --no-check-lock
• vendor/bin/pest tests/IntegrationVerificationTest.php tests/PackagingTest.php packages/vite/tests --colors=never
• composer test -- --colors=never

Note: composer cs:check is currently blocked by an existing monorepo PHPCS path issue: The file "demo/app" does not exist.

Thanks for the cleanly-scoped PR @ps-carvalho — package shape, conventions, and the additive approach are all spot on. Pushed a follow-up commit (c1f37dd) on top of yours with the maintainer-side polish so this can land:

Loud errors

• manifestTags() was returning HTML-comment fallbacks (<!-- Vite manifest not found -->, etc.) for missing/invalid manifests, missing entries, and invalid entry files. Per Marko's "loud errors" principle, those now throw a new Marko\Vite\Exceptions\ViteManifestException with helpful context + suggestions. Tests updated to match.

Framework conventions

• Removed final from ViteConfigurationException (CLAUDE.md: no final classes — blocks Preferences extensibility).
• Simplified module.php to a list-style singletons array. enabled defaults to true in ModuleManifest, the sequence: after marko/config wasn't needed (DI resolves lazily), and list-style singletons trigger autowiring directly via BindingRegistry::registerModule() so the explicit bindings entry was redundant.
• Reformatted composer.json to 4-space indent matching every other package.
• Fixed .gitattributes column alignment.

Docs

• Rewrote README.md to the slim-pointer format from docs/DOCS-STANDARDS.md.
• Added docs/src/content/docs/packages/vite.md — every package needs a corresponding docs page (we usually let the doc-updater agent handle this post-merge, but for a clean contributor PR it should ship complete).

All 13 vite tests + 21 packaging/integration tests pass; phpcs and php-cs-fixer are both clean.

Next up: per the package sequence in #17, marko/inertia is the natural follow-up — it depends on marko/vite and is where the bigger Inertia review notes from this comment come into play (real session for flash(), inject SsrTransportInterface instead of new-ing it, use marko/testing fakes). When you're ready, open it as the next stacked PR and I'll run the same review pass.

Appreciate the work 🙏
