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

-# RGHTSTA - RIGHTS comparison test
-
-`RGHTSTA.BAT` compares Novell `RIGHTS` with the current implementation.
-
-Result directories:
-
-```text
-F:\RGHTCMP\OUT       Novell baseline using \NPUBLIC\RIGHTS
-F:\RGHTCMP\PUBOUT    current implementation using \PUBLIC\RIGHTS
-F:\RGHTCMP\COMPARE.LOG
-```
-
-The test keeps the original Novell-baseline behavior and adds the public-tool
-comparison layer.
-
-Coverage:
-
-- default/current directory from `F:\`
-- explicit directory and subdirectory paths
-- explicit file and nested file paths
-- default/current directory from inside the test directory
-- relative file and relative directory paths
-- missing directory/file paths
-- too-many-arguments and `/?` usage/help cases

-operation. Its redirected output must be identical to the normal Novell output.
-That means:
-
-```text
-OUT == PUBOUT
-```
-
-Run:
-
-```bat
-F:
-CD \
-RGHTSTA
-RGHTZIP
-```
-
-The generated test tree is `F:\RGHTEST`. `RGHTZIP.BAT` packages the result and
-then removes `F:\RGHTEST` again so the SYS root stays clean.
-
-Note: `RIGHTS` currently has no short-output comparison in this baseline test. That switch exists for NDIR-style output control and should only be added to RIGHTS later if the tool implements it explicitly.
+# RGHTSTA - RIGHTS comparison test
+
+`RGHTSTA.BAT` compares Novell `RIGHTS` with the current implementation.
+
+## Run
+
+Run while logged in and with `F:` mapped to `SYS:`:
+
+```bat
+F:
+CD \
+RGHTSTA
+RGHTZIP
+```
+
+## Result layout
+
+```text
+F:\RGHTCMP\OUT       Novell baseline using \NPUBLIC\RIGHTS
+F:\RGHTCMP\PUBOUT    current implementation using \PUBLIC\RIGHTS
+F:\RGHTCMP\COMPARE.LOG
+F:\RGHTCMP\RUN.LOG
+F:\RGHTCMP\SUMMARY.TXT
+```
+
+`RGHTZIP.BAT` packages the result tree and removes the generated `F:\RGHTEST`
+test tree afterwards.
+
+## Coverage
+
+- default/current directory from `F:\`
+- explicit directory and subdirectory paths
+- explicit file and nested file paths
+- default/current directory from inside the test directory
+- relative file and relative directory paths
+- missing directory/file paths
+- too-many-arguments and `/?` usage/help cases
+
+Expected comparison:
+
+```text
+OUT == PUBOUT
+```
+
+`RIGHTS` has no `/SHORT` comparison in this test.  That switch belongs to the
+NDIR diagnostic output and should only be added to RIGHTS if the tool explicitly
+implements it later.
