fix: resolve vpr ready failures

- Fix unhandled promise in coding-agent example (void operator)
- Fix unhandled promise in cli/dev.ts (void operator)
- Fix ChildProcess.on() type error in cli/process-manager.ts
  (@types/node v25 removed .on() from ChildProcess type)
- Change example build scripts from "vite build" to "vp build"
  (vite resolves to vite-plus-core which has no CLI bin)
