#2169 canonicalizes cross-file edge targets to the root-relative file-node
id (the same id the target file gets as a node) instead of the old
absolute-path form. The #2153 baseUrl tests asserted the absolute form;
update them to the canonical id via a _cid() helper. Resolution behavior
is unchanged — only the expected id form.

Eleven cases: the webpacker repro (jsconfig + baseUrl, no paths) for
static, dynamic and extensionless specifiers; the same for tsconfig;
tsconfig winning over jsconfig in one directory; and four preservation
guards that pass before and after — declared paths and directory-prefix
aliases are not shadowed, relative imports are untouched, an absent
baseUrl changes nothing, and an external package is not fabricated.
