Broken Internal Navigation Links in README Roadmap Sections

Description Some roadmap/navigation links in the README and phase documentation do not correctly redirect to their intended sections/files. Observed issues: Certain anchor links fail on mobile GitHub view Some relative paths break when opening nested docs Navigation becomes difficult across large roadmap sections Expected behavior: All roadmap links and section anchors should correctly redirect users to the intended content across desktop and mobile GitHub interfaces. Possible fix: Standardize anchor naming Verify relative paths Add automated markdown link checking
