Add custom logo to sidebar

**Custom Branding: Use logo.png for sidebar icon**

**Changes:**
- Copied logo.png to extension directory
- Updated package.json viewsContainers icon from generic git-pull-request to logo.png
- Sidebar now shows custom Dialectic logo instead of generic icon

**Result:** Dialectic extension has distinctive branding in VSCode activity bar
