Enable Conan package caching and remove redundant doc build steps from all platform workflows. Update Makefile to ensure docs are built as part of the release target. Clean up MSVC runtime variable logic in conanfile.py and adjust Docker workflow runner and build args.
Streamlines Docker build workflow by introducing a builder target and registry-based build cache in GitHub Actions. Refactors the Makefile to improve static/dynamic build flag handling, adds MSVC support, and separates configure/build steps. Updates Dockerfile to use new Makefile targets, simplifies build context handling, and fixes artifact copying. Removes redundant Docker build targets from the Makefile and enhances Conan MSVC runtime configuration.
Introduces a STATIC flag to the Makefile for controlling static builds, passing the appropriate Conan and CMake options. Updates the Windows CI workflow to use STATIC=1 for release builds and adjusts Docker build arguments for consistency.
Refactored the Docker build workflow to use a single job with multi-platform support and removed the manifest creation step. Cleaned up the macOS build workflow by removing unnecessary Homebrew installs. Updated CPackConfig.cmake to set the install prefix by default and fixed the documentation install destination to use PROJECT_NAME.
Refactors the build-docker GitHub Actions workflow to build and push Docker images for both amd64 and arm64 architectures using a matrix strategy. Adds a manifest job to create and push a multi-arch manifest for the lthn/chain image, supporting both 'testnet' and 'latest' tags based on input.
