cmd/mcp.go (added in v3.60.0) calls Init() and LoadStorages() but skips
bootstrap.InitTaskManager(). As a result fs.CopyTaskManager,
fs.UploadTaskManager, fs.MoveTaskManager and friends are nil, and any
MCP fs_copy / fs_move on a cross-storage target panics at
internal/fs/copy.go (CopyTaskManager.Add) with a nil-pointer dereference
that the MCP handler surfaces as:
panic recovered in fs_copy tool handler:
runtime error: invalid memory address or nil pointer dereference
Mirror the cmd/server.go bootstrap order so the MCP command initializes
the task manager too.
