feat(bonfire): add Passthrough and Long command fields

- Command.Passthrough turns off cobra flag parsing and uses arbitrary
  args, so every argument after the command name, including --help, -h
  and --, reaches Run through Input.Args unchanged
- Command.Long sets cobra's Long text for the help command; without it
  the description is shown as before
- both fields are additive: commands without Passthrough parse flags and
  reject unknown ones exactly as before
- README and docs/console/writing-commands.md describe both fields

- Each `bonfire.Arg` is a positional argument with a name, a description and a `Required` marker. The usage line shows required arguments as `<name>` and optional ones as `[name]`.
- Each `bonfire.Flag` is a string flag. Set `bonfire.Flag.Bare` for a switch such as `--dry-run` that stores `true` when given alone, and `bonfire.Flag.Repeatable` for a flag that can be given several times.
- `bonfire.Command.Run` receives the context, a `bonfire.Input` and a `bonfire.Output`.
- `bonfire.Command.Long` is optional extended help shown by the help command; without it the description is shown. Set `bonfire.Command.Passthrough` for a command that forwards to another program: flag parsing is turned off, so every argument after the command name, including `--help`, `-h` and `--`, reaches `bonfire.Input.Args` unchanged. Declared flags then appear in the usage text only, and declared arguments are not count-checked.
Read arguments with `bonfire.Input.Argument`, scalar and bare flags with `bonfire.Input.Flag`, and repeatable flags with `bonfire.Input.Flags`, which returns the values in the order given:

- Styled status lines: `bonfire.Output.Info`, `bonfire.Output.Success`, `bonfire.Output.Warning` and `bonfire.Output.Error` (the last one writes to the error stream).
- Widgets: box-drawn tables (`bonfire.Output.Table`), a spinner around a function (`bonfire.Output.Spinner`) and a progress bar (`bonfire.Output.Progress`); both fall back to plain lines when output is not a terminal.
- Prompts: `bonfire.Output.Ask`, `bonfire.Output.Confirm`, `bonfire.Output.Choice` and `bonfire.Output.Secret`, which reads a hidden value on a terminal. Prompts return their defaults when input ends, and `bonfire.Output.Confirm` returns its default without asking when the session is not interactive.
- Passthrough commands (`bonfire.Command.Passthrough`) skip flag parsing, so every argument, including `--help`, reaches `bonfire.Input.Args` unchanged; this suits commands that forward to another program. `bonfire.Command.Long` adds extended help text that the help command shows instead of the description.
- Injectable streams (`bonfire.NewRootIO`, `bonfire.NewOutput`) so commands can be tested against buffers.
- In-process calls: `bonfire.Call` runs a named command with arguments against any writer (Laravel `Artisan::call`), and `bonfire.Catalog` holds an application binary's final command list so code outside the Cobra root, such as the conga scheduler, can call any registered command.
