feat(command): wire suggested values into every command definition

Ports the per-command completion metadata that PHP passes as the
suggestedValues constructor argument, resolving all TODO(cli-completion)
markers:

- CompletionTrait providers on 18 argument/option sites (installed/root/
  available package names, package types, prefer-install)
- static value lists (--format on show/outdated/search/fund/licenses/
  check-platform-reqs, archive's FORMATS, audit --ignore-severity,
  update --bump-after-update, repository's action list)
- command-specific closures: ConfigCommand::suggest_setting_keys,
  ShowCommand::suggest_package_based_on_mode, RepositoryCommand's
  suggest_repo_names/suggest_type_for_add, exec/run-script inline
  closures (downcast from the this argument, as the closures are bound
  to their concrete command in PHP)
- GlobalCommand::complete, delegating completion to the wrapped
  subcommand through CompletionInput::from_string
- a complete() override on every Composer command forwarding to
  base_command_complete (BaseCommand inheritance restoration)

Also fixes CompleteCommand to call merge_application_definition(true) as
PHP's default-argument call does; with false the application-level
"command" argument was missing from the bound definition, shifting every
argument-position detection by one.
