refactor: switch to clap with subcommands for CLI parsing
Replace hand-rolled arg parser with clap derive. Restructure as subcommands: import, cmd, script. Import subcommand supports --category, --measure, --time, --skip, --extract, --axis, --formula, --name, --no-wizard, and --output flags for configurable imports.
