fix(cli): show errors when vp install fails and bypass npm & pnpm minimum release age (#834)

## Summary
resolve #833 

- Remove `--silent` from `vp install` in `install.sh` so that pnpm/npm
errors are visible to the user instead of being silently swallowed
- Add a local `.npmrc` with `minimum-release-age=0` to the version
directory to isolate the installer from the user's global pnpm
configuration (e.g. `minimumReleaseAge` blocking recently-published
packages)

Previously, when `vp install --silent` failed (for any reason), `set -e`
would abort `install.sh` with no error output, leaving `~/.vite-plus/`
in a partial state: no `node_modules`, no `bin/` symlink, no `env` file,
and no PATH configuration.
