fix(resolver): seed locked packages into pool and honour root-require barrier

Mirror Composer's PoolBuilder/Request semantics for partial updates: each
non-allow-listed locked package becomes a non-fixed pool entry restricted to
its locked version, so `replace`-providing peers cannot silently displace
it. Path-repo packages are exempt — Composer always reloads them from disk.

Threading `--with-dependencies` through `expand_with_direct_dependencies`
now performs transitive expansion with a root-require barrier matching
UPDATE_LISTED_WITH_TRANSITIVE_DEPS_NO_ROOT_REQUIRE, so root requires stay
locked when reached via a transitive dep.

Newly green: remove_does_nothing_if_removal_requires_update_of_dep,
update_allow_list_removes_unused, github_issues_4795,
partial_update_with_deps_warns_root.
