Release v0.1.1

Changes

Added

• install() rules and generated CMake package-config files (hyperliquid-config.cmake, hyperliquid-config-version.cmake, hyperliquid-targets.cmake) so the library can be consumed via find_package(hyperliquid CONFIG REQUIRED) after cmake --install / vcpkg install
• HYPERLIQUID_BUILD_TESTS and HYPERLIQUID_BUILD_EXAMPLES CMake options — default ON for top-level builds, automatically OFF when the project is consumed via add_subdirectory/FetchContent

Changed

• target_compile_features(hyperliquid PUBLIC cxx_std_20) — the C++20 requirement now propagates to consumers through the exported target
• Raised minimum CMake version from 3.20 to 3.21 (required for PROJECT_IS_TOP_LEVEL)
