feat(javascript): resolve exact package import aliases (#1862)
* feat(javascript): resolve exact package import aliases
Resolve exact #alias specifiers against the importer's enclosing
package.json imports map using the shared condition, array, and null
target selection. Nested packages keep their own maps; missing keys,
explicit nulls, and out-of-scope aliases report a precise reason.
Wildcard, recursive, and external-package import targets remain
unresolved.
* fix(javascript): keep nested import aliases in CLI graphs
Bound nested #alias requires produce application-graph require edges
from the enclosing package. Node reports MODULE_NOT_FOUND when a nested
package.json has no imports field, without inheriting the ancestor map.
* fix(javascript): resolve literal package import keys before path admission
* fix(javascript): preserve import keys and invalid-target fallback
* fix(javascript): preserve unmatched package target arrays
* fix(javascript): retain package target refusal evidence
* test(browser): match real verifier startup budget
