Direct /:dir/... routes do not register the project in the sidebar #18943

Description

Description

When opening OpenCode through a direct directory route such as:

• /:dir/session
• /:dir/session/:id

the main view enters the correct directory context, but the sidebar does not automatically show that directory as an opened project.

As a result:

• the project button does not appear in the sidebar
• the full session list for that project is not shown in the sidebar
• the user has to manually open/add the project once before the sidebar becomes consistent

This looks like a frontend state-registration bug in the direct-route entry path.

OpenCode version

1.3.0

Steps to reproduce

1. Open OpenCode with a direct route like /{base64(directory)}/session
2. Or open /{base64(directory)}/session/{id}
3. Observe that the main area is in the correct directory
4. Observe that the sidebar does not show the project as opened

Actual behavior

The direct route creates the directory context, but does not register the project into the sidebar's opened-project state.

Expected behavior

Direct route entry should behave the same as manually opening a project:

• the project should appear in the sidebar
• the project session list should load automatically
• duplicate entries should not be created

Notes

From local source inspection, manual project opening already goes through a shared project-open path that is idempotent and also triggers session loading.

The direct /:dir/... route appears to resolve the directory successfully, but does not call the same project-open registration path.
