Funnel for remote development

[ajhalili2006]

Add support for remote development in the VSCode Tailscale extension.

• package.json

  • Add remote to extensionKind to specify the extension's capabilities for remote environments.

• src/extension.ts

  • Modify the activate function to detect if the extension is running in a remote context by checking the vscode.env.remoteName property and adjust the behavior accordingly.
  • Update commands and UI elements to handle remote-specific scenarios, such as opening terminals and managing SSH configurations.

• src/config-manager.ts

  • Add support for detecting the remote context and adjusting configurations accordingly in the ConfigManager class.
  • Update the Config interface to include properties specific to remote environments, such as remoteHost, remotePort, and remoteUser.
  • Modify the set and setForHost methods to handle remote-specific configurations and ensure that these methods can set and persist configurations for both local and remote environments.
  • Update the withGlobalStorageUri method to initialize remote-specific configurations if the extension is running in a remote context.

• src/config-manager.test.ts

  • Create automated tests for the extension using vitest to cover different remote environments such as SSH, Dev Containers, and GitHub Codespaces.

• .github/workflows/test.yml

  • Integrate the testing of remote environments into the existing continuous integration (CI) pipeline.
  • Add steps to the CI pipeline to set up and test the extension in SSH, Dev Containers, and GitHub Codespaces.

Didn't intend to create this merge request from Copilot Workspace pending manual human testing. Here's the link to the snapshot if needed.

I might close this issue instead if I think that didn't work.
