feat: make rookify execute on run only

[boekhorstb1]

• Add run to execute and run --help per default
• Add short version for CLI

closes #87

.venv/bin/rookify
usage: Rookify [-h] [-d] [-s] [run]

positional arguments:
  run                Run the migration.

options:
  -h, --help         show this help message and exit
  -d, --dry-run
  -s, --show-states  Show states of the modules.

Dear @boekhorstb1,

I like the intention of not execute Rookify by mistake. Therefore I would love to see --dry-run to be replaced by a --run parameter as like suggested you would construct a command line like rookify --dry-run run to execute Rookify in dry-run mode. This is a bit counter-intuitive.

How about the following changes:

• Run Rookify in dry-run mode by default (remove dry-run parameter)
• Add a parameter like --migrate with default False to do the actual work

[boekhorstb1]

rookify --dry-run run

Hi @NotTheEvilOne !

I think it would look rather like this, if it preflight mode should be used only:

rookify run --dry-run 
# or
rookify run -d

We could add the migrate parameter. But Im not sure how.
Another idea. How about we change it like this:

rookify migrate --dry-run
# or
rookify migrate -d

that way you can run rookify without arguments and still get --help per default.
If you would want to truly migrate, you would run:

rookify migrate

[boekhorstb1]

Alright, we came to the following decision:

Going to use --dry-run as default, when no args given

reason: less is more

[boekhorstb1]

Looks now like this:

 .venv/bin/rookify --help
usage: Rookify [-h] [-d] [-s] [-m]

options:
  -h, --help         show this help message and exit
  -d, --dry-run
  -s, --show-states  Show states of the modules.
  -m, --migrate      Run the migration.
