fix(console): flatten Application inheritance to restore overrides

Composer\Console\Application embedded Symfony's Application as an
`inner` field and delegated to it, so polymorphic calls inside the
Symfony base (e.g. doRun -> $this->getLongVersion()) resolved to
Symfony's own methods and never reached Composer's overrides. As a
result `--version` bypassed Composer's getLongVersion()/doRun()
entirely.

Flatten the PHP inheritance chain into the single shirabe Application
struct: take in the Symfony base methods (parent-calling overrides kept
under a `base_` prefix) and drop the `inner` delegation. Replace the
Symfony Application struct in shirabe-external-packages with an
`Application` trait that the merged struct implements, so commands and
descriptors can reference it without a reverse crate dependency.
