fix: update page title in inactive browser tabs

[meteyou]

Description

This PR fixes the page title not updating in inactive browser tabs (especially in Firefox). The issue was caused by vue-meta not receiving reactivity updates when the browser throttles JavaScript execution in background tabs.
The fix removes vue-meta entirely and replaces it with a direct document.title assignment via a Vue @Watch decorator. This approach is consistent with how the favicon is already updated and works reliably in inactive tabs.

Changes:

• Remove vue-meta dependency from package.json
• Remove vue-meta import and plugin registration from main.ts
• Replace metaInfo() method with a @Watch('title') that sets document.title directly in App.vue

Pull request overview

This PR fixes a bug where browser tab titles fail to update when the tab is inactive, particularly in Firefox. The root cause is that vue-meta doesn't receive reactivity updates when browsers throttle JavaScript execution in background tabs. The solution removes vue-meta entirely and implements direct document.title manipulation via a Vue @Watch decorator, matching the existing pattern used for favicon updates.

Key Changes:

• Removed vue-meta dependency and its registration
• Replaced metaInfo() method with @Watch('title') decorator that directly sets document.title
• Simplified the title getter to a single computed property
