Pull request overview

Prepares the compositor for future “overlay” work by introducing a workspace “type” concept (currently only Normal) and plumbing it through workspace creation/selection, session-management persistence, and tree-query/CLI introspection.

Changes:

• Introduce WorkspaceType on WorkspaceNode and rename/create APIs around “normal” workspaces (ensure_normal_workspace, create_normal_workspace, etc.).
• Persist/restore workspace type in session-management toplevel state (wire format bumped to V2).
• Expose workspace type via jay_tree_query (wire event + CLI JSON/text output) and add a TOML config/spec placeholder for workspaces.
