Function parseCommand

parseCommand(argv: string[]): Command
Parse an issue_tree command line into a typed Command.

Help is detected first (via detectHelp) and always wins: a bare invocation, a help subcommand, or --help/-h anywhere on the line yields a HelpCommand without ever reaching the strict option parser — which matters because parseArgs would otherwise throw on the unknown --help option. Only when help is not requested does an empty or unknown subcommand throw.
Parameters
- argv: string[]
  arguments after the node/script entries (subcommand first)
Returns Command
the parsed, discriminated command
Throws
Error on a missing or unknown subcommand, or a bad flag (help paths never throw)
Example
```
parseCommand(['render', '--format', 'svg']).subcommand  // => 'render'
  parseCommand([]).subcommand                              // => 'help'
  parseCommand(['render', '--help']).subcommand            // => 'help'
```
