Add a curated C / C++ / POSIX standard-header allow-list and consult it before resolving angle includes: a known stdlib header (<vector>, <stdio.h>, …) is classified external up front and never probed against -I dirs, so it can never bind to an in-tree file sharing its basename. Angle includes are now resolved through the -I search path otherwise. Stdlib-header imports surface under a dedicated resolution-outcome reason, and external-call synthesis treats C-family stdlib headers as external.
