[Bug]: About page can show 0.4.6.15 as latest, then recheck to "already latest 0.4.6.14"

What happened?

On ego lite 0.4.6.14, About (chrome://settings/help) can show a phantom newer version:

• current: 0.4.6.14
• latest: 0.4.6.15
• button: 重新启动以更新 / Relaunch to update

After opening About again, the same page rechecks and becomes:

• ego 已是最新版本
• 版本 0.4.6.14（正式版本）lite (arm64)

There is no 0.4.6.15 package on any official channel. ego-browser upgrade and Omaha both return no update. The user is told to restart for a version that does not exist.

Steps to reproduce

1. Run ego lite 0.4.6.14 on macOS arm64.
2. Open chrome://settings/help while an update check is stale or mid-flight.
3. Observe current 0.4.6.14 + latest 0.4.6.15 + relaunch CTA.
4. Stay on the page or reopen About and wait for the on-demand check.
5. Observe the page flip to "already latest 0.4.6.14".

Independent checks at the same time:

ego-browser upgrade
# ego lite is already up to date.

ego-browser nodejs <<'EOF'
cliLog(JSON.stringify(await getBrowserVersion()))
EOF
# {"currentVersion":"0.4.6.14","updateAvailable":false}

# Official DMG
# https://cdn.ego.app/setup/macos/arm64/egolite.dmg
# x-amz-meta-omaha-version: 0.4.6.14
# last-modified: Fri, 14 Aug 2026 13:57:34 GMT

# Omaha POST https://update.citrolabs.ai/service/update2
# updatecheck.status = noupdate

# https://lite.ego.app/changelog latest heading: ego (lite) 0.4.6.14
# No 0.4.6.15 heading exists.

Expected behavior

About, getBrowserVersion(), ego-browser upgrade, Omaha, changelog, and the official DMG should agree. If 0.4.6.15 is not published, the UI must not show it as latest or ask the user to relaunch.

Version

ego lite 0.4.6.14 (official / lite arm64)

Environment

macOS 26.5.0, Apple Silicon, Claude Code

Additional context

This is an app/updater UI bug, not something the open package/ego-browser runtime can ship a binary fix for. Filing so the About / Omaha display path can stop advertising an unpublished version.

No open-source runtime PR for this one — About / Omaha live in the closed-source app.

Related: #287 / #289 cover the empty help() catalog on the same 0.4.6.14 install. Official channels (Omaha, DMG, changelog, ego-browser upgrade) all still say 0.4.6.14 is latest.
