tests: add Novell DOS tool baseline suite

Add DOS-side baseline scripts for the Novell tools used to compare the
reimplemented public utilities.

The suite covers the current baseline set:

  MAP
  SLIST
  WHOAMI
  LOGIN / LOGOUT
  NDIR
  NCOPY
  FLAG
  FLAGDIR
  CREATOR
  RIGHTS
  GRANT
  REVOKE
  REMOVE

It also includes supporting trustee, rights, rename, move, delete and
file-operation tests.

Each test writes reproducible output into a per-tool CMP directory and
provides a matching ZIP helper for collecting the results. The ZIP
helpers clean generated test trees afterwards so SYS: does not keep
accumulating temporary directories.

This is the Novell baseline layer only. A later change can extend the
same scripts to run the full comparison cycle:

  NPUBLIC baseline -> PUBLIC implementation -> NPUBLIC control

+# MARS dosutils tests
+
+This directory contains DOS-side regression and compatibility tests for `mars-dosutils`.
+
+The tests are grouped by feature so that Novell reference-tool checks and our own tool regressions stay separated but easy to compare.
+
+## Directory layout
+
+| Directory | Purpose |
+| --- | --- |
+| `flag/` | File/directory attribute tests, Novell `NPUBLIC\FLAG` baseline and MARS `PUBLIC\FLAG` regression notes. |
+| `flagdir/` | Planned: directory-specific FLAG and recursive attribute tests. |
+| `grant/` | Planned: trustee grant tests. |
+| `rights/` | Planned: effective-rights and trustee readback tests. |
+| `map/` | Planned: MAP command and login-script mapping tests. |
+| `login/` | Planned: LOGIN/NLOGIN compatibility tests. |
+| `logout/` | Planned: LOGOUT/NLOGOUT compatibility tests. |
+
+## Naming
+
+DOS-executed files should use 8.3 names. Keep Novell reference tests and MARS tests close together, but name them clearly.
+
+Suggested suffixes:
+
+- `*N.BAT` for Novell-only baseline tests using `NPUBLIC`/`NLOGIN`.
+- `*M.TST` or `*M.BAT` for MARS/dosutils tests using `PUBLIC`/`LOGIN`.
+- `*CMP.BAT` for comparison/helper scripts.
+
+## Expected workflow
+
+1. Run the Novell baseline test first.
+2. Check the MARS NWE server log for the expected NCP path and completion codes.
+3. Run or implement the matching MARS/dosutils regression test.
+4. Keep notes in the feature directory `README.md`.
