Summary

Commit 1: Add ZKB float window, Chinese ship type names, and language persistence

• Add ZKBMonitor floating window showing real-time zkillboard kills with configurable opacity, max kills, and region
  filtering
• Fetch and cache Chinese ship type names from ESI, display when UI language is zh-CN
• Persist language selection across restarts by applying it before UI initialization
• Add ZKB float window preferences to the Preferences dialog (both en-US and zh-CN)
• Add ShipTypeDisplay property to ZKB data model for language-aware ship type display
• Add build-release.ps1 script for creating single-file releases

Commit 2: Bundle Chinese ship type names as built-in resource

• Add ShipTypesCN.dat with 677 pre-fetched zh-CN ship type names
• Load Chinese ship names from built-in data directory first, then merge user cache
• Removes the need for users to fetch Chinese names from ESI at runtime
• Add ShipTypesCN.dat to project output for distribution

Test Plan

• Builds with 0 errors
• ZKB monitor window opens and fetches kill data
• Chinese ship type names display when language is zh-CN
• Language setting persists across app restart
• ShipTypesCN.dat loaded from built-in data at startup
• No ESI calls needed for Chinese ship names
