[/-] [+]PR #602 needs follow-up

[pascalandr]

Context

PR #602 consolidated desktop state restoration and server-owned session behavior after PR #578.

Two session states still need follow-up work:

• Yolo mode is now owned by the CodeNomad server but is kept only in memory, so it is lost when the workspace or server restarts.
• The expanded/collapsed state of sessions and nested subsessions is no longer restored after restarting CodeNomad

OpenCode PR anomalyco/opencode#23068 added client-controlled session metadata to the create, get, update, list, and fork APIs. CodeNomad already uses this mechanism for metadata.codenomad.worktreeSlug.
