[BUG] Creating a project from a template does not apply the manifest

[Ben Elgar]

When we create a project using one of the templates that templates manifest should be automatically applied upon creation.

There are two reasons this doesn't happen right now:

1. #482, which means that we would start all of the components, which isn't what we want.
2. I'm not clear on how to best get a handle on a workspace from within a kernel function. Specifically, I'm not sure how to get a reference to a relevant Workspace struct from within here:

   exo/internal/core/server/kernel.go

   Lines 80 to 117 in 535bb90

    func (kern *Kernel) CreateProject(ctx context.Context, input *api.CreateProjectInput) (*api.CreateProjectOutput, error) { 
    	projectDir := input.Root 
    	if !filepath.IsAbs(projectDir) { 
    		return nil, errors.New("path must be absolute") 
    	} 
     
    	var templateDir string 
    	if input.TemplateURL != nil { 
    		var err error 
    		templateDir, err = template.GetTemplateFiles(ctx, *input.TemplateURL) 
    		if err != nil { 
    			return nil, fmt.Errorf("getting template files: %w", err) 
    		} 
    	} 
     
    	if templateDir != "" { 
    		err := os.Rename(templateDir, projectDir) 
    		if err != nil { 
    			if os.IsExist(err) { 
    				return nil, dirExistsErr 
    			} 
    			return nil, fmt.Errorf("moving project dir: %w", err) 
    		} 
    	} else { 
    		if err := os.Mkdir(projectDir, 0750); err != nil { 
    			if os.IsExist(err) { 
    				return nil, dirExistsErr 
    			} 
    			return nil, fmt.Errorf("making project dir: %w", err) 
    		} 
    	} 
     
    	result, err := kern.CreateWorkspace(ctx, &api.CreateWorkspaceInput{Root: projectDir}) 
    	if err != nil { 
    		return nil, fmt.Errorf("creating workspace: %w", err) 
    	} 
    	return &api.CreateProjectOutput{WorkspaceID: result.ID}, err 
    }
