Introduces a new Makefile target 'docker-chain-node' to build the lthn/chain Docker image. Updates the lthn-chain Dockerfile with improved comments, sets BUILD_TESTNET=1 by default, and clarifies multi-stage build targets. Also updates the docs submodule reference.
Deleted the crowdin.yml configuration file and updated the lthn-chain Dockerfile. The Dockerfile now sets NO_COLOR=1 to disable color escape characters, adds logic to symlink testnet binaries to mainnet names for consistency, and re-enables the chain-service stage using mainnet binary names.
Standardized build target names and artifact directory paths across Linux, macOS (Intel and ARM), and Windows GitHub Actions workflows. Updated Dockerfile to use 'gcc-linux-armv8' as the build target and added 'bison' to dependencies for improved build environment consistency.
Renamed and updated CMake build profiles for consistency across platforms, added a new gcc-linux-armv8 profile, and removed legacy build scripts and utilities from the utils directory. Introduced Docker build context and documentation for containerized builds. Updated docs submodule reference.
