👀 Migrate features from the AuroraEditor Sidebar

[KaiTheRedNinja]

Describe the solution you'd like

The AuroraEditor fork will be merging features back into CodeEdit. This issue will be tracking the sidebar features we will be migrating over which includes:

• [ ] #479
• [x] #1137 (similar to VS Code)
• [x] #1140
• [x] #1018
• [x] #1060
• [ ] #1139
• [x] #1138

Additional context

Any git related features need extra work as the AE and CE git systems are completely different.

This PR may also require the workplace client to be recoded to match the AE FileSystemClient.
