refactor: replace the in-tree DI container with internal/container

[roxblnfk]

🔍 What was changed

• Replaced DLoad's in-tree DI container (Service\Container, Module\Common\Internal\ObjectContainer, Service\Factoriable) with the internal/container package — the same code, extracted and grown.
• Config hydration is no longer a hard-coded namespace check inside the container's make(). It moved into a ConfigInflector registered as an Internal\Container\Inflector, and config classes now opt in with a #[InflectableConfig] marker attribute.
• Input\Build and Input\Destination gained the marker too, so their #[InputOption] values are now hydrated (they sat outside the old Module\Config\Schema\ prefix and were silently never hydrated before).

How it works

• Every object the container produces passes through the registered inflectors; ConfigInflector hydrates only the ones carrying #[InflectableConfig] and returns the rest untouched.
• Bootstrap now holds the concrete ObjectContainer (the default), because addInflector() is not part of the Container interface.
• The inflector resolves Logger lazily from the container: it is built during withConfig(), before the logger is registered, so a constructor dependency would fail.

Why?

• Removes a maintenance fork of the container so both DLoad and Trap track one package, and turns the DLoad-specific namespace hook into a generic, reusable inflector.

Checklist

• How was this tested:
  • composer test locally — 498 passed, 4 skipped; the Acceptance suite drives the real CLI reading dload.xml, so config hydration through the inflector is covered end-to-end.
  • composer psalm clean; composer cs:fix reports no changes.
  • No new unit tests added — behaviour is covered by the existing suite (StabilityTest updated for the moved Factoriable FQCN).

Review notes

• In this dev tree internal/container is also bundled and replaced by testo/testo, whose copy still carries @internal on the class; the cross-package calls in Bootstrap are therefore baselined in psalm. The lock still pins the real internal/container 1.0.1 from Packagist, so a --no-dev install resolves it correctly.
• yiisoft/injector stays in require; no project code imports it any more, so it could be dropped (it remains a transitive dependency of internal/container).
