This pull request updates our Docker build environment and dependencies to use newer, more secure, and feature-rich versions. The main changes involve upgrading the Dockerfile syntax version, updating the BuildKit and related tool versions, and bumping the versions of key build tools (uv and sccache). These updates help ensure better compatibility, security, and performance in our build pipeline.

Build environment and toolchain upgrades:

• Upgraded the Dockerfile syntax directive from version 1.20.0 to 1.22.0 in all Dockerfiles, enabling new Docker build features and improvements. [1] [2] [3] [4] [5]
• Updated the BuildKit image used in both the GitHub Actions workflow (build-image.yml) and the local build script (test-build-local.sh) from v0.27.1 to v0.28.0, including the corresponding SHA256 digest for security. [1] [2]

Dependency version bumps:

• Upgraded the uv tool to version 0.10.9 (from 0.9.28) and updated its release timestamp and SHA256 checksums for both x86_64 and aarch64 architectures in stage3/Dockerfile.
• Upgraded the sccache tool to version 0.14.0 (from 0.13.0) and updated its release timestamp and SHA256 checksums for both x86_64 and aarch64 architectures in stage3/Dockerfile.
