v1.11.1-rc9

• additions:
  • Added unixstl::system_traits<>::get_current_process_path() and winstl::system_traits<>::get_current_process_path() (multibyte and wide), obtaining the current process image path with an optional basename path-separator out-parameter;
  • Added T_resizeableBuffer overloads of get_current_process_path() on unixstl / winstl system_traits (query → stlsoft::resizeable_buffer_resize() → fill; ppFile only after the final fill; resize failure sets ENOMEM / ERROR_OUTOFMEMORY and leaves the buffer unchanged);
  • unixstl::filesystem_traits<wchar_t> — implemented find_last_path_name_separator() / find_next_path_name_separator() and is_path_rooted() / is_path_absolute() / is_path_UNC() (NUL-terminated and counted), including Windows drive-letter and UNC classification;
  • unixstl::filesystem_traits<wchar_t> — path-resolve, current-directory, and directory-enumeration members remain declared, pending one conversion policy for that group;
  • unixstl_C_get_home_directory_w() (unixstl/system/directory_functions.h) — reads HOME via getenv() and converts with mbstowcs() (locale multibyte encoding); a short buffer keeps a NUL in the last slot and returns cchBuffer - 1, matching the narrow copy;
  • unixstl::system_traits<wchar_t> — implemented path_str_compare() and path_str_n_compare() (on Windows, case-folded with towupper() and treating / and \ as equivalent);
  • unixstl::system_traits<wchar_t> — implemented get_environment_variable() (raw and resizeable-buffer) by converting the name with wcstombs(), reading it with getenv(), and converting the value with mbstowcs(); implemented the resizeable-buffer overload of get_home_directory();
  • unixstl::system_traits<wchar_t> — load_library() and free_library() stay declared together pending one conversion policy (free_library() no longer calls dlclose() alone); expand_environment_strings() remains declared;
• testing:
  • Component tests test/component/unixstl/system/process_paths (multibyte; multi-OS raw path oracle; resizeable-buffer overloads for auto_buffer / vector, ppFile, and resize-failure) and test/component/winstl/system/process_paths (multibyte and wide; GetModuleFileName oracle; same resizeable-buffer coverage);
  • Unit tests test.unit.unixstl.filesystem.filesystem_traits cover wide separator finding and path classification, and agreement with the narrow specialisation;
  • Unit tests test.unit.unixstl.system.system_traits cover wide path_str_compare() and path_str_n_compare();
  • Component tests test.component.unixstl.system.system_traits cover wide get_home_directory() and get_environment_variable() (probe, fixed buffer, and std::vector resizeable overload) via platformstl::environment_variable_scope;
  • Resizeable-buffer cases shared with the resizeable-buffer line (ensure_dir_end() / remove_dir_end(), and the narrow resizeable get_home_directory() / get_environment_variable() overloads) remain empty pending that merge;
  • test.unit.versions — aligned with 1.11.1-rc9 (_STLSOFT_VER_1_11_1_RC9);
• docs:
  • Normalised Doxygen \pre comments to bare boolean expressions (no outer parentheses; no trailing ; / .);
  • Prefer nullptr over NULL / prose in \pre text; optional-buffer forms use zero-length check first (0 == n || nullptr != s);
  • Converted expressible prose preconditions (e.g. !empty(), n <= size(), nullptr != p) where applicable; retained soft COM / prior-init / exception-gated contracts as prose;
