Benny Yen 3e71c87708 refactor(updates): fetch version from registry instead of npm CLI to support multiple managers (#446)
## Background  
Addressing feedback from
https://github.com/openai/codex/pull/333#discussion_r2050893224, this PR
adds support for Bun alongside npm, pnpm while keeping the code simple.

## Summary  
The update‑check flow is refactored to use a direct registry lookup
(`fast-npm-meta` + `semver`) instead of shelling out to `npm outdated`,
and adds a lightweight installer‑detection mechanism that:

1. Checks if the invoked script lives under a known global‑bin directory
(npm, pnpm, or bun)
2. If not, falls back to local detection via `getUserAgent()` (the
`package‑manager‑detector` library)

## What’s Changed  
- **Registry‑based version check**  
- Replace `execFile("npm", ["outdated"])` with `getLatestVersion()` and
`semver.gt()`
- **Multi‑manager support**  
- New `renderUpdateCommand` handles update commands for `npm`, `pnpm`,
and `bun`.
  - Detect global installer first via `detectInstallerByPath()`  
  - Fallback to local detection via `getUserAgent()`  
- **Module cleanup**  
- Extract `detectInstallerByPath` into
`utils/package-manager-detector.ts`
- Remove legacy `checkOutdated`, `getNPMCommandPath`, and child‑process
JSON parsing
- **Flow improvements in `checkForUpdates`**  
  1. Short‑circuit by `UPDATE_CHECK_FREQUENCY`  
  3. Fetch & compare versions  
  4. Persist new timestamp immediately  
  5. Render & display styled box only when an update exists  
- **Maintain simplicity**
- All multi‑manager logic lives in one small helper and a concise lookup
rather than a complex adapter hierarchy
- Core `checkForUpdates` remains a single, easy‑to‑follow async function
- **Dependencies added**  
- `fast-npm-meta`, `semver`, `package-manager-detector`, `@types/semver`

## Considerations
If we decide to drop the interactive update‑message (`npm install -g
@openai/codex`) rendering altogether, we could remove most of the
installer‑detection code and dependencies, which would simplify the
codebase further but result in a less friendly UX.
