feat(cli): update check + self update

[Leechael]

Summary

• Adds lightweight update notification with 200ms hard timeout and 24h TTL.
• Adds phala self update to upgrade the CLI using the detected package manager/runtime.
• Keeps utilities silent; all user-facing output is routed through commands/dispatcher.

Design notes (why this approach)

• PDM-style philosophy: no detached worker/daemon; keep a tiny bounded time window (200ms) and fail silently to avoid impacting UX.
• JSON safety: no update notice in --json or when JSON mode is enabled.
• Cache-first UX: if updateCheckLatest_* indicates a newer version, we can notify without re-checking the network.
• Security: self-update executes package manager via argv (no shell string injection) and validates --channel as a dist-tag token.

Channels (stable vs prerelease)

• Stable users track latest by default.
• Prerelease builds (e.g. x.y.z-beta.n) default to channel beta.
• Override via PHALA_UPDATE_CHANNEL, config updateCheckChannel, or phala self update --channel <tag>.
• Caches are separated per channel:
  • updateCheckLastAt_<channel> / updateCheckLatest_<channel> (e.g. _latest, _beta)
  • Backward compat for stable: updateCheckLastAt / updateCheckLatest still written for latest.

UX

• Disable update notice:
  • PHALA_DISABLE_UPDATE_CHECK=1
  • phala config set disableUpdateNotice true

Implementation

• Update check entrypoints: cli/src/core/update-check.ts + cli/src/core/dispatcher.ts
• Self update command: cli/src/commands/self/update
• Package manager detection: cli/src/core/package-manager.ts

Tests

• Unit tests cover skip conditions, caching, scoped package encoding, dist-tag channel selection, and timeout.
