Subject: [PATCH] fix(ci): repair Profiling Tests (Weekly) workflow on main

CMake configure was failing with "Could NOT find GTest (missing:
GTEST_LIBRARY GTEST_INCLUDE_DIR GTEST_MAIN_LIBRARY)" because the
workflow installed apt build tools but never ran `conan install`.
GTest is provided via Conan (gtest/1.14.0) per conanfile.py and
required by find_package(GTest REQUIRED) in CMakeLists.txt.

Switch to the canonical pattern used by _required.yml:
- Use the .github/actions/install-build-deps composite action
  (installs clang-18, cmake, ninja, AND conan with detected profile)
- Cache ~/.conan2 keyed on conanfile.py hash
- Run `conan install` for Release before cmake configure
- Pass -DCMAKE_TOOLCHAIN_FILE=build/conan-deps/conan_toolchain.cmake
  so find_package() locates GTest
