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

+# FLAGDIR automated test
+
+Novell FLAGDIR baseline using `NPUBLIC\FLAGDIR`.
+
+`FLAGDIR` uses long option names, not the short FLAG names.
+
+Supported options shown by the tool:
+
+```text
+Normal
+System
+Hidden
+Deleteinhibit
+Purge
+Renameinhibit
+```
+
+## Run
+
+Run while already logged in and with `F:` mapped to `SYS`.
+
+```text
+FDGTSTA
+FDGTZIP
+```
+
+Result:
+
+```text
+F:\FDGCMP\FDGTSTA.ZIP
+```
+
+Linux package with server log:
+
+```sh
+sudo ./mars_packtest_v3.sh fdgtsta 5 mario
+```
+
+## Coverage
+
+- directory flag display
+- `Normal` reset
+- set `Hidden`, `System`, `Purge`
+- set `Deleteinhibit` and `Renameinhibit`
+- NDIR directory readback
+- NDIR filters for visible flags
+- final reset/readback
