v0.7.0

Added

• Fluent validation rule builder Vortex\Validation\Rule with inline per-rule message support; Validator::make() now accepts rule objects.
• Fluent response/session flash helpers: Response::with(), withMany(), withErrors(), withInput(), and session batch helpers Session::flashMany() / flashPutMany().
• Request-aware response shortcuts: Response::error(), notFound(), forbidden(), and unauthorized() that auto-select HTML or JSON output.

Changed

• Request::wantsJson() now treats X-Requested-With: XMLHttpRequest as JSON-preferring requests.
• Breaking: composer.lock is no longer tracked in the repository and is now ignored.
