Subject: feat(resolver): honor --ignore-platform-reqs and wildcard patterns

The pool builder and rule-set generator only consulted an exact-match
HashSet, so `--ignore-platform-reqs` (no value) and `--ignore-platform-req=ext-foo-*`
fell through to the SAT layer and produced "no matching package found"
for transitive platform deps. Track the bool flag separately and run
each platform name through `mozart_core::matches_wildcard` against the
configured patterns.

Unblocks four installer fixtures:
install-{ignore-platform-package-requirement-wildcard,ignore-platform-package-requirements}
update-{ignore-platform-package-requirement-wildcard,ignore-platform-package-requirements}.
