fix(plugin-vue): ensure HMR updates styles when SFC is treated as a type dependency

[jh-leong]

Description

close vuejs/core#13008

Fix HMR when an SFC exporting a type is treated as a type dependency. Ensure the SFC itself triggers an update instead of relying only on type dependency handling, preventing outdated transforms from applying and causing incorrect updates.
