* cli: added --safety=full|none flag to maintenance commands This allows selection between safe, high-latency maintenance parameters which allow concurrent access (`full`) or low-latency which may be unsafe in certain situations when concurrent Kopia processes are running. This is a breaking change for advanced CLI commands, where it removes timing parameters and replaces them with single `--safety` option. * 'blob gc' * 'content rewrite' * 'snapshot gc' * pr renames * maintenance: fixed computation of safe time for --safety=none * maintenance: improved logging for blob gc * maintenance: do not rewrite truly short, densely packed packs * mechanical: pass eventual consistency settle time via CompactOptions * maintenance: add option to disable eventual consistency time buffers with --safety=none * maintenance: trigger flush at the end of snapshot gc * maintenance: reload indexes after compaction that drops deleted entries, this allows single-pass maintenance with --safety=none to delete all unused blobs * testing: allow debugging of integration tests inside VSCode * testing: added end-to-end maintenance test that verifies that full maintenance with --safety=none removes all data
