refactor: use environment consumer to detect SSR

[btea]

Replace the deprecated opt.ssr transform option with this.environment.config.consumer === 'server' in both plugin-vue and plugin-vue-jsx.

The ssr flag on the transform hook options is deprecated in favor of the environment API. Using environment.config.consumer is the recommended way to determine whether the current transform runs in a server (SSR) environment.

this.environment was introduced in v6.0, but plugin-vue and plugin-vue-jsx supports Vite 5. Maybe we can cut a new major with babel 8, dropping Vite 5,6,7, Node 20.

Yeah, this looks good.

@sxzz @edison1105 any thoughts?

LGTM, also suggest required node version "node": "^22.18.0 || ^24.11.0 || >=26.0.0".
