Skill Sync v0.1.3

What's new

• Change-count badges on status filters - see exactly how many uploads, downloads, conflicts, and deletes are pending at a glance.
• Themed metric cards with a dedicated delete metric.
• Open skill directory - open any Skill's folder straight from the app.
• Localized README screenshots - English and 简体中文 previews now in the README.

Fixes

• De-duplicate identical blobs when uploading multiple Skills (avoids redundant work and Vault churn).
• Badge alignment and conflict-metric color fixes.
