fix: add file_exists check to ensureCompiled in-memory cache guard (#97)

The in-memory cache in ensureCompiled() assumed that once a view was
compiled, the compiled file would always exist on disk. When compiled
views are cleared (e.g. via artisan view:clear) while the process is
still running, the stale cache entry causes require_once to fail with
a file-not-found error.

Adding a file_exists($compiledPath) check alongside the isset() guard
ensures the compiled file is re-created when it has been removed.

Fixes #96
