Desktop deep links can open projects before they are recognized

Description

Desktop deep links do not always open a project correctly.

When an open-project or new-session link contains a directory that is not in the local project list, the client can open the directory before the server recognizes it. The new layout also uses a different path from the legacy layout.

The app should ask the server to recognize the directory first. It should then add the project and open its session page. Both layouts should use the same process.

Plugins

None relevant.

OpenCode version

Local dev build.

Steps to reproduce

1. Start OpenCode Desktop with the new layout.
2. Use an opencode://open-project or opencode://new-session link for a directory that is not in the project list.
3. Open the link.
4. The app can navigate before the server recognizes the project, so the project does not open correctly.
