feat(cli): fall back to package manager for vp run without vite-plus dependency

[fengmk2]

When vp run <script> is executed in a project without vite-plus in
dependencies or devDependencies, fall back to <pm> run <script> directly
from the Rust layer instead of entering the JS delegation flow. This avoids
unnecessary overhead of downloading Node.js runtime and prompting users to
install vite-plus.

• Add has_vite_plus_dependency() utility that walks up from cwd to find
  the nearest package.json and checks for vite-plus
• Add run_script_command() / resolve_run_script_command() on
  PackageManager for executing <pm> run <args>
• Add run_or_delegate module that checks dependency before routing
• Add unit tests for dependency detection and command resolution
• Add snap test verifying fallback behavior with pnpm
