refactor(scripts): use vp run -t for dependency-aware example build

Replace the manual `pnpm --filter ... && pnpm --filter ...` chain with
viteplus's transitive task runner. `vp run -t @pkg#task` runs the task
in the target package and all its workspace dependencies in
topological order, derived from the regular `package.json` workspace
deps, so the chain stays correct even if more workspace packages are
added later. Also opens the door to free task-level caching.
