feat: refactor execution

[otaviomacedo]

This change introduces the creation and execution of stack refactors. It builds on previous work that put all the pieces in place (mapping computation, mapping file reading, exclude lists, dry-run etc). The following flowcharts summarize the behavior in interactive and non-interactive modes, for each environment in the application:

Non-interactive case

flowchart LR
    mapping{Refactor file present?}
    empty{Empty mapping?}
    dryrun{--dry-run?}
    compute[Compute mapping]
    use[Use mapping]
    print[Print mapping]
    mapping ---|No| compute
    mapping ---|Yes| use
    compute --- empty
    use --- empty
    empty ---|Yes| Exit
    empty ---|No| print
    print --- dryrun
    dryrun ---|Yes| Exit
    dryrun ---|No| Refactor
    Refactor --- Exit
