fix(update): apply --minimal-changes preferred versions on partial update

The previous --minimal-changes wiring only populated the policy's
preferred-version map when no packages were named on the CLI, so a
partial update like `update foo --with-all-dependencies
--minimal-changes` saw an empty map and the resolver picked the highest
matching version for transitive deps that should have stayed at their
lock version. Mirror Composer's
`Installer::createPolicy(minimalUpdate=true)` directly: build the map
from the lock and skip only the packages explicitly named by the user
(the `updateAllowList`), so deps unlocked transitively by
`--with-(all-)dependencies` still prefer their lock version when the
constraint allows it.
