"Check for Updates…" menu action gives no feedback on macOS

[dpav02]

Clicking T3 Code → Check for Updates… on macOS appears to do nothing — no dialog, no toast, no visible change — regardless of whether the app is up to date or the check fails.

This was previously reported in #359 (v0.0.3 → v0.0.4, Apple Silicon). That issue was closed after the reporter saw the sidebar rocket icon on a later update, but the underlying problem — no feedback from the menu action — was never fixed. The suggestion to install from the .zip instead of the .dmg does not change the behavior either.

Steps to reproduce

1. Install T3 Code v0.0.10 on macOS (DMG or ZIP, same result)
2. Click T3 Code → Check for Updates… in the menu bar
3. Nothing happens — no dialog, no indication the check ran

Expected behavior

A native dialog confirming the result, e.g. "You're up to date!" or an error message — consistent with how other macOS apps handle this menu action (VS Code, Chrome, etc.).

Root cause

handleCheckForUpdatesMenuClick() in apps/desktop/src/main.ts fires checkForUpdates("menu") as fire-and-forget (void). The sidebar update button intentionally hides for "checking" and "up-to-date" states (desktopUpdate.logic.ts:25-33), so there is no visible feedback path for the menu-triggered check.

Environment

• T3 Code v0.0.10
• macOS 26.3.1 (25D2128), Apple Silicon
