Pull Request Overview

This PR removes CGO dependencies from the build process following the removal of the pg_query_go dependency. The changes simplify the build configuration by eliminating CGO-specific tooling and switching to native Go cross-compilation.

Key Changes:

• Removed CGO build tools (gcc, g++, musl-dev) and runtime dependencies (libc6-compat) from Docker configuration
• Replaced Docker-based cross-compilation with native Go cross-compilation in CI workflows
• Updated documentation to reflect CGO-free build commands
