Share session history with the copilot vs code extension

### Describe the feature or problem you'd like to solve

Would love the ability to resume the sessions of a same project or workspace between the copilot vs code extension and the copilot cli

### Proposed solution

Similar to how the codex cli and codex desktop apps work together and share agent sessions, this would allow us developers to resume sessions started with the cli in the vs code extension and vice versa. This provides a great experience for example for remote work from a phone or another computer through ssh. Also provides cool features with codespaces and servers or containers with vs code installed.

### Example prompts or workflows

Someone works on a project in vs code on a server and has to leave their workstation. Later remotely connects through ssh to their machine that has vs code (e.g. from their phone) and continue working remotely.
