v1.11.1-rc8

• additions:
  • Added stlsoft_C_environment_variable_strtoll_m() and stlsoft::environment_variable_strtoll(), with UNIX getenv() / strtoll() and Windows getenv_s() / STLSOFT_C_AUTO_BUFFER support; added component tests;
  • Added unixstl_C_get_current_process_id() (unixstl/process/functions.h, new), winstl_C_get_current_process_id() (winstl/process/functions.h), and platformstl_C_get_current_process_id() (platformstl/process/functions.h, new), in terms of getpid() / _getpid();
  • unixstl::filesystem_traits — added rewind_dir() (wrapping rewinddir()) to complement open_dir(), read_dir(), and close_dir(), so that a directory search may be restarted from its first entry without closing and reopening the handle;
• fixes:
  • Fixed stlsoft_C_environment_variable_exists_m() when getenv_s() reports an existing empty variable; added component tests for stlsoft::environment_variable_exists();
  • unixstl::filesystem_traits — class_type is now defined in terms of char_type (the wide-character specialisation previously named the narrow specialisation);
  • unixstl / winstl system_traits and filesystem_traits — canonicalised the conditional-compilation guards (no behavioural change);
• testing:
  • Component tests for unixstl::filesystem_traits (test/component/unixstl/filesystem/filesystem_traits/opendir) cover open_dir(), read_dir(), rewind_dir() (before any read, after a partial read, after exhaustion, on an empty directory, and repeatedly), and close_dir();
  • Scratch test test/scratch/unixstl/filesystem/rewind_dir — exercises rewind_dir() over a directory given on the command-line;
  • Example examples/by_project/unixstl/filesystem/rewind_dir — enumerates a directory in two passes (count, then collect), using rewind_dir() between them;
  • test.unit.versions — aligned with 1.11.1-rc8 (_STLSOFT_VER_1_11_1_RC8);
• version:
  • unixstl — 1.8.6 beta 7 (_UNIXSTL_VER_1_8_6_B07), with STLSoft 1.11.1-rc8;
  • winstl — 1.13.0 beta 4 (_WINSTL_VER_1_13_0_B04), with STLSoft 1.11.1-rc8;
  • inetstl — 1.5.0 alpha 3 (_INETSTL_VER_1_5_0_A03), with STLSoft 1.11.1-rc8;
• boilerplate:
  • Added run_all_component_tests.sh / .cmd, run_all_performance_tests.sh / .cmd (with --gap-groups), and run_all_automated_tests.sh / .cmd (unit then component; --unit-only / --component-only);
  • Added generate_doxygen.sh, Doxyfile, and doc/mainpage.md — HTML API documentation generated from the public headers into _build/doxygen/html;
  • remove_cmake_artefacts.sh — no longer removes docs or Doxyfile; iterates arrays safely;
  • batch_compile_check, execute_performance_tests.sh — quote the $(dirname ...) directory resolution;
  • Scripts — build_cmake.sh, clean_cmake.sh, ctest_cmake.sh, prepare_cmake.sh, remove_cmake_artefacts.sh, run_all_examples.sh, and run_all_scratch_tests.sh rewritten to the common Synesis helper-script layout: builds go through cmake --build (with --config selected from SIS_CMAKE_CONFIG for multi-config generators) rather than make / mingw32-make; coloured output (-A / --always-use-colours, SIS_CMAKE_ALWAYS_USE_COLOURS, NO_COLOR); quoted paths and arguments; .sis/project_name.txt used in all status messages;
  • prepare_cmake.sh — added --build-shared-libs and -s / --stlsoft-root-dir; honours SIS_CMAKE_GENERATOR and SIS_CMAKE_MINGW; every -D option is passed on all generator paths;
  • run_all_unit_tests.sh / .cmd — now run unit-test programs only (--unit-only accepted for compatibility; --component-only removed);
  • run_all_examples.sh — retains --skip-interactive (.github/ci_skip_interactive_examples.txt, which prevents headless CI hanging on GUI examples) and its discovery of every executable under the examples tree, and now exports SIS_EXAMPLE_SMOKE=1; run_all_scratch_tests.sh / .cmd — removed --verbosity;
  • .gitattributes — Linguist language-bar policy: public C headers and sources are classified as C, C++ headers and sources as C++, and *.cmake as CMake; helper scripts, IDE project files, CMakeLists.txt, and makefile are excluded from the advertised language mix (-linguist-detectable);
  • CI — ci-cell.yml runs component tests via run_all_component_tests.sh;
  • INSTALL.md — documented run_all_component_tests.sh, run_all_automated_tests.sh, and generate_doxygen.sh; corrected the unit-test discovery patterns;
