fix(resolver): expose locked branch-alias entries in the pool

Composer's Locker::getLockedRepository runs each locked package through
ArrayLoader::load, which materializes any extra.branch-alias as a
separate AliasPackage in the locked repository. Mozart was only adding
the base locked package to the pool, so a `dev-master` locked entry
with branch alias `2.2.x-dev` was invisible to numeric root constraints
like `~2.1` on a partial update — the resolver bailed with "no matching
package found" even though Composer accepts the same lock. Surface
each branch-alias as a sibling pool entry pointing at the base via
is_alias_of.
