build: publish HAS_<Pkg> for detected Synesis packages (#49)

* build: publish HAS_<Pkg> for detected Synesis packages

After each successful detection of a Synesis package other than STLSoft,
define HAS_<Pkg> and HAS_<PKG>. Dots in package names become underscores.
BDUT and CLASP, already all-caps, get the single macro. Client-prefixed
presence macros were removed where only the client read them. Dependency
switches such as XTESTS_HAS_SHWILD, PANTHEIOS_HAS_SHWILD, and the *_NO_*
contracts stay.

* fix: align versions links and current release symbols

Keep versions target_link_libraries in the signature the project already
uses, link header-only packages by their imported target, and compare
version tests with the current release symbol.

* fix: use an if for C versions efferent headings

The && fputs heading expression trips -Werror=unused-value. Print the
heading from an if, as the C++ reporters already do.

 # cstring - Changes <!-- omit in toc -->
 
 
+## 4.1.0-beta2 - 27th October 2026
+
+* Defined `HAS_shwild` / `HAS_SHWILD` and `HAS_p99` / `HAS_P99` when those packages are detected;
+* Unit tests **test.unit.insert-replace** and **test.unit.status-codes** include **shwild** under `CSTRING_HAS_SHWILD`, and **test.scratch.versions** prints **shwild** under `HAS_shwild`;
+
+
 ## 4.1.0-beta1 - 21st October 2026
 
 * Brought the tip CMake runners up to **misc-dev-scripts** 0.6.2 and merged that gold into **prepare_cmake.sh**, keeping the cstring `-D` flags and `--gap-groups`;
