Implement Docker Web project management on top of workspace_id while keeping host mode workspace behavior intact.
Backend changes:
- Move Docker user files to users/<user>/projects/<project_id>/{project,data,logs} and shared user state to users/<user>/personal.
- Add automatic legacy migration from old project/data/logs/agentskills layouts and from the temporary project/shared layout.
- Generate project IDs server-side from the project name, reserve internal IDs, and hide project paths from the UI.
- Add project rename/delete APIs; deleting a Docker project removes its project directory and releases terminal/container state.
- Add host workspace rename/delete APIs; deleting a host workspace only removes catalog entries and keeps files on disk.
- Scope Docker containers, terminals, uploads, conversations, storage, and running task metadata by workspace_id.
- Store private skills under users/<user>/personal/agentskills and sync them into each project workspace.
- Inject the current project/workspace name through prompts/workspace_system.txt.
Frontend changes:
- Replace Docker file-tree area with project management UX and reuse host multi-workspace running-task behavior.
- Add a management dialog for creating, renaming, and deleting projects/workspaces.
- Show project labels instead of internal IDs in toasts and project lists.
- Clear stale conversation history during project/workspace switching and show loading until the new list is ready.
- Keep running-task loader/check behavior consistent across host workspaces and Docker projects.
