Is your feature request related to a problem? Please describe.
Currently, when using OpenCode Desktop, making code edits or quick tweaks requires switching context to an external editor. For independent developers who handle end-to-end workflows, frequently toggling between the desktop client and an external IDE disrupts focus, breaks the flow state, and reduces overall productivity.

Describe the solution you'd like
I propose embedding a lightweight VS Code instance (or Monaco Editor) directly into OpenCode Desktop, similar to the implementation seen in Trae (SOLO). This would allow users to review, edit, and save code natively within the OpenCode environment without ever leaving the application.

Describe alternatives you've considered
An alternative would be adding deep-link integrations (e.g., vscode://) to open specific files or lines in an external editor. However, this still requires opening another window and doesn't solve the core friction of context switching.

Additional context
Integrating a familiar and powerful editor interface natively would massively improve the user experience and keep developers immersed in the OpenCode ecosystem. Trae (SOLO) is a great benchmark for how smooth this embedded experience can be.
