`depot status` and `depot get` chose a local depot tree with `--target local`, resolving the root from `DEPOT_DIR`. That split one decision over two flags and left `--target local` valid with no directory anywhere. Adopt the nwsync convention instead: `--out DIR` names the tree on disk in the same breath as choosing it, and `--target` now names remote backends only. The two are mutually exclusive. `--target local` stays as a deprecated alias for `--out $DEPOT_DIR` so existing callers keep working, and `status --source` is now ignored with a warning instead of silently accepted. Also split positionals off by hand in `depot get`, so the documented `depot get <sha> <dest> --out DIR` form parses its flags at all — Go's flag package stops at the first positional. Closes #66
