Two files that both import and use the same type as a bare name (e.g.
`from pathlib import Path` used as a type hint in a.py and b.py) collapsed into one
node, even with no project definition to anchor them. The referencing file is now
recorded in an internal `origin_file` field and used as the disambiguation key when
_disambiguate_colliding_node_ids splits same-id nodes — while source_file stays
empty, so the corpus-level rewire still collapses these stubs onto a real project
definition when one exists (the #1402 path is untouched). origin_file is read only
inside disambiguation; the rewire and the Java/C# type resolvers key off
source_file as before.
Ported from PR #1479 by @jiangyq9 (squash-merged onto current v8; the branch's
stale base made the raw diff appear to revert later features — the 3-way merge
applies only the surgical origin_file change). Resolved a test-adjacency conflict
with #1500 by keeping both cross-file tests.
