feat(cli): parse the Composer CLI with bpaf combinatorsfeat/cli-parse

Add a cli module that reproduces every command's argument/option set
from the PHP configure() definitions using bpaf combinators (no derive).
Output is per-command typed structs plus a top-level Command enum; the
bridge into Symfony Console Input is deferred. Verbosity is unified into
the global option and bump-after-update models VALUE_OPTIONAL as a
three-state enum. Known limitation (bundled subcommand short flags) is
recorded as a TODO in the module.
