0.11.0

Version 0.11.0

Changelog

• Added mbo::testing::IsElementOf(container) — element-on-the-left orientation of gmock's Contains. Iterates with raw operator== (with a std::pair component-wise fallback) so heterogeneous subject types (string literals, std::string_view, etc.) compile without caller-side conversion, on both libc++ and libstdc++.
• Added mbo::testing::IsKeyOf(map) — convenience matcher for "is this value among the keys of the map?". Failure messages report "is a key of {…}".
• Added mbo::testing::IsValueOf(map) — parallel to IsKeyOf for mapped values. Failure messages report "is a value of {…}".
• Bumped Bazel to 9.1.1 (.bazelversion).
• Updated module dependencies: bazel_skylib 1.8.2 → 1.9.0, platforms 1.0.0 → 1.1.0, rules_cc 0.2.14 → 0.2.19, rules_shell 0.6.1 → 0.8.0, re2 2025-11-05 → 2025-11-05.bcr.1, googletest 1.17.0 → 1.17.0.bcr.2, google_benchmark 1.9.4 → 1.9.5, helly25_bashtest 0.1.0 → 0.3.0, toolchains_llvm 1.5.0 → 1.7.0, depend_on_what_you_use 0.7.0 → 0.16.0, and the hedron_compile_commands pin.
• helly25_bashtest 0.3.0 loads the sh_* rules from @rules_shell directly, so Bazel 9 (which no longer autoloads the legacy native sh_* rules) needs no --incompatible_autoload_externally workaround.
• Bumped abseil-cpp 20250814.1 → 20250814.2. Held at the 20250814 series because newer Abseil (20260107+) deprecates the absl::MutexLock(Mutex*) constructor that re2 2025-11-05 still uses, which fails under --cxxopt=-Werror.
• Bumped the pinned LLVM toolchain 17.0.4 → 20.1.8. LLVM 17.0.4's bundled linker segfaults against the macOS 26 SDK when building tools in the exec configuration (e.g. //mbo/diff:diff, which _diff_test builds with cfg=exec); 20.1.x links cleanly and compiles the tree without new -Werror warnings.
• Migrated the _diff_test is_windows select off the deprecated @bazel_tools//src/conditions:host_windows to @platforms//os:windows.
• Fixed compilation under clang 21 (e.g. Apple clang on macOS 26): its tightened constexpr rules reject placement-construct_at into a const-qualified object, so struct_names_clang.h and limited_vector.h now store the non-const value type.
