Description: This PR modernizes simplecpp's header lookup to more closely match GCC/Clang, while preserving backward compatibility for existing users. What's new Typed, ordered search paths Introduce DUI::SearchPath with PathKind: Include (for -I) SystemInclude (for -isystem) Framework (for -F, Darwin) SystemFramework (for -iframework, Darwin) If DUI::searchPaths is non-empty, it is honored verbatim in the order provided. If it's empty, legacy includePaths are mirrored as Include entries for back-compat. CLI flags Add support for -F

and -iframework (framework lookups). Add support for -isystem (system include lookups). Keep -I as before. Public API convenience New helpers on DUI: addIncludePath(path, legacy=false) addSystemIncludePath(path) addFrameworkPath(path) addSystemFrameworkPath(path) addIncludePath defaults to legacy=false; tests exercise both modes. Darwin frameworks Framework includes like are resolved to Pkg.framework/{Headers,PrivateHeaders}/Hdr.h. Implement toAppleFrameworkRelatives() returning prioritized candidates (Headers first, then PrivateHeaders). Works for both __has_include and normal #include. Lookup order (summary of actual implementation) For "quotes" includes only: directory of the including file (unchanged). Interleaved searchPaths in left-to-right CLI order: Include (-I) Framework (-F) — using the Headers/PrivateHeaders rewrite when applicable System include paths (SystemInclude, i.e., -isystem) System framework paths (SystemFramework, i.e., -iframework) (Standard library dirs are outside simplecpp's scope; -idirafter/-iquote are not implemented in this series.) Core loader refactors openHeader() and FileDataCache::get() now consult typed, ordered paths and produce candidates accordingly. When resolving framework headers, both Headers and PrivateHeaders are tried in that order. Tests & tooling Integration tests New helpers to build fixtures: generic headers, sources, and minimal framework trees. test_framework_lookup: verifies Headers vs PrivateHeaders and -F vs -iframework. test_searchpath_order: a single parametrized test that validates precedence across -I, -isystem, -F, -iframework, including interleaving and duplicates, asserting on the exact #line path chosen. Unit tests (test.cpp) Framework handling covered for both #include and __has_include. Back-compat exercised by running key tests twice (new ordered API and legacy mode via addIncludePath(..., /*legacy=*/true)). Supersedes the following pull request: #448 Related issues: Fixes #283
