Three cobra commands forming the CLI surface: - root: fetch and filter weekly deals (--store/--zip with BOGO, category, department, query, and limit filters) - stores: list nearby Publix locations by ZIP code - categories: show available deal categories with counts Structured error system with typed error codes (INVALID_ARGS, NOT_FOUND, UPSTREAM_ERROR, INTERNAL_ERROR) and semantic exit codes (0-4). Errors render as human-readable text or JSON depending on output mode. Robot-mode features: auto-JSON when stdout is not a TTY, compact quick-start help when invoked with no args, and JSON error payloads for programmatic consumers.
