fix: Rspack throw error when using ForceCompleteRuntimePlugin (vercel#85221)

TODO: Rspack currently does not support the hooks and chunk methods
required by `ForceCompleteRuntimePlugin`.

Temporarily disable `ForceCompleteRuntimePlugin` when using Rspack as
the bundler.

This plugin ensures complete webpack runtime is available during soft
navigation to prevent runtime function errors, but Rspack currently does
not support the required compilation hooks and chunk graph APIs.
