feat(cli): add prdy, quality-rails, and wizard subcommands

Wires @mosaic/prdy, @mosaic/quality-rails, and @mosaic/mosaic into the
unified CLI binary. The wizard subcommand uses dynamic import to avoid
loading heavy wizard deps for other commands. Adds @types/node to cli
devDependencies and guards @mosaic/mosaic index.ts program.parse() so
the module is safely importable without auto-executing.
