Detect Vite+-managed Codex installs (#42071)

## Why

Vite+ launches Codex through the same JavaScript shim as npm, so Codex could
misidentify Vite+-owned installations and recommend npm for updates.

## What changed

- Detect Vite+ global installs from their package ownership metadata and pass a
  dedicated `CODEX_MANAGED_BY_VITE_PLUS` marker to the native binary.
- Represent Vite+ in install context and `codex doctor` output.
- Recommend `vp install -g @openai/codex` in update and repair flows for
  Vite+-managed installs.

See https://github.com/openai/codex/pull/30880.
