Pull request overview

This PR extends the project’s minimal CMake preset reader to support include directives in preset JSON files, enabling presets to be composed across multiple files (including recursive includes) and supporting limited macro expansion in include paths.

Changes:

• Add recursive traversal of preset include graphs when resolving presets.
• Implement limited macro expansion for include paths (${hostSystemName} and $penv{VAR}), with errors on unsupported macros.
• Expand and refactor tests to cover include behavior, recursion, relative path resolution, and macro expansion.

• _walk() yields the implicit project file(s) before the current file’s explicit include list. Because _get_preset() returns the first match, this makes presets from user-included files lower-precedence than project presets, which contradicts the stated “user presets take precedence over project presets” behavior when a user include defines the same preset name as the project file. Traverse explicit includes before implicit convention-includes so user-side includes still override project presets.

        for include_path in implicit:
            yield from self._walk(include_path, visited=visited)

        for include_path in preset_file.includes:
            if self._load_file(include_path) is None:
