feat: implement Phase 3 CLI Polish - Error handling, output formatting, completions

Implements comprehensive CLI improvements for Hatch: Error Handling: - Add structured CLIError type with exit codes - Add consistent exit codes (OK, GeneralError, UsageError, NetworkError, ServerError, ConfigError) - Add colored error messages with details - Add proper connection refused error handling Output Formatting: - Add ANSI color support with terminal detection - Add colored success/error/warning messages - Add compact output format option - Add --output flag for json/table/compact formats Shell Completions: - Add bash completions with full command/flag support - Add zsh completions with descriptions and subcommand handling - Add fish completions with helper functions - Add PowerShell completions with native argument completer - Add hatch completions <shell> command Configuration Support: - Add config file support (XDG_CONFIG_HOME or ~/.config/hatch/config.json) - Add environment variable overrides (HATCH_URL, HATCH_FORMAT, NO_COLOR) - Add hatch config show/set/get/init commands - Add configuration keys: server_url, format, no_color, timeout Additional Improvements: - Add version command with build-time version injection - Add help command with colored usage output - Add --output flag to all commands for format control - Add request timeout support - Improve error messages with actionable suggestions - Add comprehensive test coverage Co-Authored-By: Paperclip <noreply@paperclip.ing>
