Research direction

Investigate how Vue implements the v once directive in its compiler (see src/compiler/directives/). Mpvue's compiler is based on Vue's, so replicate the logic for mpvue's template transformation. Ensure that v once works for mini program templates. Look at existing directives like v if or v for for guidance on how they handle in mpvue. No existing PRs or comments provide additional context.
