EricBuild v1.7.1

🚀 New Features

• File Explorer — Browse your project files in a dedicated side panel with filtering, toolbar actions (new file/folder, collapse all, refresh), and tree navigation.
• Conversation History — View, search, pin, archive, and delete past conversations from a dedicated history panel. Conversations are grouped by time (Today, Yesterday, Last 7 Days, etc.) with a context menu for quick actions.
• Editor Integration — Opening a file that's already in an editor tab focuses it instead of opening a duplicate.

⚡ Improvements

• Orchestration Panel — Panel width is now remembered between sessions, including collapsed state.
• File Rename Sync — Renaming a file updates the editor tab title automatically.

🐛 Bug Fixes

• Fixed the About page GitHub link, logo, and copyright year.
