[NFR]: Introspection

[niden]

Goal: answer "what is this application, and what does it do?" without reading source.

Design calls this out as disproportionately valuable under ADR, where routing is convention plus attributes over a namespace and there is no routes file to read.

• list (aliases commands, enumerate)
• route:list : every route the app answers, in router precedence order.
• config:show : resolved project configuration, including which values were inferred rather than declared
• container:list : services registered in Phalcon\Container\Container.
• event:list : registered listeners.
