fix(show-command): un-ignore 10 tests by fixing show-warnings typing and repo bugs

Replace the PhpMixed-based `$showWarnings` hack in VersionSelector::
findBestCandidate with a typed ShowWarnings enum (Always / Predicate),
letting ShowCommand::findLatestPackage pass its real closure instead of
hardcoding `true`. Fix the --no-dev branch in ShowCommand::execute,
which built `repos` from an empty package list instead of sharing the
same InstalledRepository as `installed_repo`. Pass repository handles
instead of pre-borrowed `&dyn RepositoryInterface` refs into get_package/
generate_package_tree/add_tree to stop a RefCell double-borrow panic on
--all/--locked. Add the missing CompletePackage/RootPackage
set_release_date setter so the outdated sorting-by-age test can set
fixture dates. Resolve OutputFormatterStyleStack::pop's empty-style
todo!() via clone_box(), and fix FileDownloader's cache-GC log call to
pass the VERY_VERBOSE verbosity PHP uses.
