Overman fails to start if unrecognised flag is passed to it (e.g. `overman start --help` hangs)

[dombarnes]

Working example:
overman start -f Procfile.dev

Not working - shows no output. Never exits
overman start -o -f Procfile.dev

Expected Behaviour: Overman ignores the flag, or throws an unrecognised flag error.

Version: 0.87.3
Ruby: 3.2.2

I just made a very similar mistake, passing my env file as the Procfile, also never exits

$ overman start -f default.env

It is also weird that overman start --help doesn't work (but overman --help does)

$ overman --help
Commands:
  overman check                   # Validate your application's Procfile
  overman export FORMAT LOCATION  # Export the application to another process management format
  overman help [COMMAND]          # Describe available commands or one specific command
  overman run COMMAND [ARGS...]   # Run a command using your application's environment
  overman start [PROCESS]         # Start the application (or a specific PROCESS)
  overman version                 # Display Foreman gem version

Options:
  -f, [--procfile=PROCFILE]  # Default: Procfile
  -d, [--root=ROOT]          # Default: Procfile directory

$ overman start --help
^C07:52:20 system | SIGINT received, starting shutdown
^C07:52:20 system | SIGINT received, starting shutdown
07:52:20 system | sending SIGTERM to all processes

$ overman help start
Usage:
  overman start [PROCESS]

Options:
  -c, [--color], [--no-color]          # Force color to be enabled
  -e, [--env=ENV]                      # Specify an environment file to load, defaults to .env
  -m, [--formation="alpha=5,bar=3"]    # Specify what processes will run and how many. Default: "all=1"
  -p, [--port=N]
  -t, [--timeout=N]                    # Specify the amount of time (in seconds) processes have to shutdown gracefully before receiving a SIGKILL, defaults to 5.
      [--timestamp], [--no-timestamp]  # Include timestamp in output
                                       # Default: true
  -f, [--procfile=PROCFILE]            # Default: Procfile
  -d, [--root=ROOT]                    # Default: Procfile directory

Start the application (or a specific PROCESS)

[dentarg]

Same issue (hangs, no output) when you leave out the process count in start -m / start --formation

• bad: overman start -m worker
• works: overman start -m worker=1
