feat(console): resolve phase-b TODOs in doRun and IO wiring

Wire up ConsoleIO with HelperSet/QuestionHelper, register the
ErrorHandler with the IO instance, and fall back to a default output
in run(). Replace resolved phase-b TODOs across the console, command,
io, factory, installer, dependency_resolver, and util modules; reclassify
the remaining blockers (typed Symfony command registry, stdin resource
caching) as phase-c.
