dosutils: align Novell-compatible tests and stage NCOPY work

Update the DOS utilities and test suite with the current Novell comparison
state.

Validated/updated tool behavior:
- improve CREATOR output by showing Novell-style attribute and rights masks
- extend FLAGDIR handling with old NCP22 directory attribute read/write
  fallback paths
- expand NDIR Novell-style formatting, filtering, /SUB handling, date output,
  DI/RI attribute display and richer metadata collection
- adjust REVOKE output/grammar, recursive /SUBDIRECTORIES behavior and trustee
  update/delete paths to better match Novell tools
- adjust SLIST header/output behavior for logged-in and logged-out cases
- update README status to reflect the currently green/tested tools

Test-suite changes:
- add/refresh Novell comparison tests for CREATOR, NDIR, REVOKE and SLIST
- update NCOPY tests and collection scripts for the current investigation state
- refresh per-tool README files and top-level test documentation
- keep MAP documented as still separately open

NCOPY:
- add the current NCOPY implementation and experimental NCP74/server-side-copy
  scaffolding
- build ncopy.c so it stays compile-tested
- keep NCOPY disabled in the NET multicall dispatch for now because the
  server-side-copy/open-handle path is still unsafe and needs further analysis

Build:
- include ncopy.c in the DOS utility build
- drop the temporary MARS_DOSUTILS_VERSION define wiring from CMake

-Automated Novell-only baseline for `NPUBLIC\NDIR`.
+Automated compare test for `NDIR`.
 
 ## Run
 
 ```text
+SET LGNTPWD=dein-supervisor-passwort
+F:
+CD \

 ```
 
-Results:
+`LGNTPWD` is required because the test switches to `NOPASSUSER` and then logs back in as `SUPERVISOR` through the maintainer-only `LOGIN /PWD:` path.

+
+## Notes on /SHORT
+
+`/SHORT` is a MARS DOS tools helper option. Novell NDIR does not know this option,
+so the test keeps `/SHORT` output in `SHORTOUT` and `USHORT` only. These files are
+packaged for manual inspection but are not part of the byte-for-byte Novell compare.
+
+
+Additional user/trustee matrix
+------------------------------
+The extended matrix also creates F:\TNDIR\USR with trustees for multiple
+objects that exist in the default test environment:
+
+- USER NOPASSUSER
+- USER MARIO
+- USER GUEST
+- GROUP EVERYONE
+
+The delayed NOPASSUSER phase reads the same tree through NPUBLIC and PUBLIC
+NDIR.  This gives more coverage for effective-rights output: direct user
+trustees, group/EVERYONE trustees, unrelated user trustees, inherited rights,
+and Supervisor-on-child cases.
