- Updated JSON resolver to use gjson library for JSON5 support (comments, trailing commas) - Added --json flag to CLI tool for JSON output format - Added typed getter methods: GetInt(), GetUint(), GetFloat(), GetBool(), GetBytes() - GetBytes() supports human-readable formats like "10G", "20KiB" via go-humanize - Fixed YAML interpolation to always quote output values for safety - Updated README to clarify YAML-only input and automatic quoting behavior - Added .gitignore to exclude compiled binary - Fixed test config files to use unquoted interpolation syntax - Updated tests to expect quoted interpolation output
