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

+# FILER tests
+
+Manual Novell FILER baseline with pre/post output comparison.
+
+## Files
+
+| File | Purpose |
+| --- | --- |
+| `FILPREN.BAT` | Pre-FILER setup and baseline output capture. |
+| `FILPOSTN.BAT` | Post-FILER output capture, compare, and cleanup. |
+| `FILCMPN.BAT` | Repeat PRE/POST comparisons only. |
+| `FILTSTM.TST` | MARS/dosutils regression notes/spec for the scenario. |
+
+## Test flow
+
+```text
+FILPREN.BAT
+NPUBLIC\FILER
+FILPOSTN.BAT
+```
+
+Optional repeat compare:
+
+```text
+FILCMPN.BAT
+```
+
+## Output comparison
+
+`FILPREN.BAT` writes baseline files to:
+
+```text
+F:\TFILE\PRE\*.OUT
+```
+
+`FILPOSTN.BAT` writes post-FILER files to:
+
+```text
+F:\TFILE\POST\*.OUT
+```
+
+Then `FC` compares:
+
+```text
+FLAGA.OUT
+FLAGB.OUT
+FLAGK.OUT
+NDIR.OUT
+DATES.OUT
+RIGHTS.OUT
+TRUST.OUT
+TRUSTA.OUT
+```
+
+No differences are expected if FILER was only used for inspection.
+Intentional differences are expected if attributes or metadata were changed in FILER.
+
+
+
+## Manual changes to perform in FILER
+
+The FILER screen starts at `MARS\SYS:NPUBLIC`. Use the menu to navigate and make a small, controlled change set.
+
+### 1. Go to the test directory
+
+Use:
+
+```text
+Select Current Directory
+```
+
+Change to:
+
+```text
+F:\TFILE
+```
+
+or the equivalent NetWare path:
+
+```text
+MARS\SYS:TFILE
+```
+
+Then use:
+
+```text
+Directory Contents
+```
+
+You should see:
+
+```text
+A.TXT
+B.TXT
+KEEP.TXT
+SUBDIR
+```
+
+### 2. Inspect file and directory information
+
+Open/inspect the information screen for:
+
+```text
+A.TXT
+B.TXT
+KEEP.TXT
+SUBDIR
+SUBDIR\C.TXT
+```
+
+Just opening these screens should exercise the server info-readback paths without changing anything.
+
+### 3. Make one or more intentional attribute changes
+
+Use FILER to change only a few obvious attributes, so the `PRE` versus `POST` compare is easy to understand.
+
+Suggested changes:
+
+```text
+A.TXT       Hidden: toggle
+B.TXT       Read Only: toggle
+KEEP.TXT    Archive Needed: toggle
+```
+
+If FILER allows editing directory attributes, also inspect `SUBDIR`, but keep directory changes minimal.
+
+### 4. Optional no-change pass
+
+For a pure readback test, do not change anything in FILER. Then `FILPOSTN.BAT` should show no `FC` differences except harmless output/date formatting differences.
+
+### 5. Expected compare results
+
+After leaving FILER, run:
+
+```text
+FILPOSTN.BAT
+```
+
+Expected results:
+
+```text
+No FILER changes:
+  FC should report no differences for the PRE/POST files.
+
+Changed A.TXT Hidden:
+  FLAGA.OUT, NDIR.OUT, DATES.OUT may differ.
+
+Changed B.TXT Read Only:
+  FLAGB.OUT, NDIR.OUT, DATES.OUT may differ.
+
+Changed KEEP.TXT Archive Needed:
+  FLAGK.OUT, NDIR.OUT, DATES.OUT may differ.
+
+Changed rights/trustees:
+  RIGHTS.OUT and/or TRUST*.OUT may differ.
+```
+
+The important part is that the differences match the intentional FILER changes and the server log shows no unexpected completion codes.
+
+## Server log focus
+
+Look for:
+
+```text
+NCP22/25
+Set Directory/File Information
+change bits
+nwp_stat
+nw_optain_file_dir_info
+nw_search_file_dir
+build_d_i
+```
