Match the layout convention used by every other multi-addon-shape fork
in Exiles/ (Bagnon/, Kui_Nameplates/, ShadowedUnitFrames/, etc.) — the
addon's own files live in a subfolder named after the addon, with only
the repo-level README files at the root.
All moves are pure git renames (history preserved). Toc references are
relative to the toc location so nothing inside the addon changes.
