Description

The plugin already ships the shared pre-push hook, and CI verifies it against the canonical copy, but the hook dispatches on phpstan/phpstan.created.neon and phpstan/phpstan.modified.neon and analyses nothing at all without them, so until now it has been a no-op here.

This adds both. Created files are held at level 9, since a new file carries no pre-existing debt; touched files inherit the plugin's level 5. Both include the plugin's existing phpstan.neon, and CI analyses only that file, so CI is unaffected.
