PR #2069 by 1rashiid and ksylvan: feat(cli): add --workflow for sequential pattern composition

• Added a --workflow flag that chains multiple patterns together from a YAML or JSON file, piping each step's output into the next step's input.
• Preserved compatibility with existing flags, including --stream, --dry-run, -m/-V, --context, --strategy, and --language, while leaving the single-pattern -p path untouched.
• Added pre-flight validation that catches empty steps, missing or repeated patterns, and unknown pattern names before any LLM call is made.
• Added per-step overrides for input, model, vendor, and variables, with progress and error messages prefixed as [step N/TOTAL pattern] on stderr to keep stdout pipe-clean.
• Added shell completions for --workflow in Bash, Zsh, and Fish, including workflow file path suggestions.
