* bump gopkg.in/yaml.v3 * test: cannot remove local items with cscli * test dangling links * test: cannot install local item with cscli * pkg/cwhub: reorg (move) functions in files * allow hub upgrade with local items * data download: honor Last-Modified header * fatal -> warning when attempting to remove a local item (allows remove --all) * cscli...inspect -o yaml|human: rename remote_path -> path * Correct count of removed items Still no separate counter for the --purge option, but should be clear enough
