* shell: add -delete option to remote.copy.local
Add a -delete flag to remote.copy.local that removes files and
directories from remote storage when they no longer exist locally,
similar to rsync --delete. This makes the command usable for
scheduled one-shot backups that also propagate local deletions.
- -include/-exclude patterns also limit which remote files are deleted
- size/age filters only apply to copying, since remote entries have no
local attributes to filter on
- orphaned remote directories are removed after their contents,
deepest first, and only when no name filter is set (a recursive
RemoveDirectory could otherwise remove intentionally kept files)
- deletion is skipped entirely if any copy failed
- -dryRun shows DELETE lines for review before committing to anything

* shell: fix remote.copy.local -delete deleting files outside -dir
Traverse lists remote objects by key prefix with no delimiter, so a -dir
pointing at a subdirectory also matches siblings that merely share its
name prefix (foo -> foobar). Those are not under the local traversal
root, so -delete treated them as extraneous and removed them. Scope
deletion candidates to paths under dirToCopy.
Also drop the directory-removal path: RemoveDirectory is a no-op on every
backend and Traverse never emits directory entries, so it only ever
printed success for work it never did.
