Rename app from er_xdg_pipe_menu to xdg_pipe_menuHEADmain

Drop the "er-" prefix throughout: module/atom names, filenames,
socket paths, and docs. It was an implementation detail, not part
of the app's identity.

-%% @doc Locates .desktop files under the XDG application directories.
-%%
-%% Directory precedence follows the XDG Base Directory Specification:
-%% the user's data home (most specific, so its entries should win over
-%% system ones downstream) is searched first, then each directory in
-%% `XDG_DATA_DIRS'. Each of `XDG_DATA_HOME' and `XDG_DATA_DIRS' falls
-%% back to its spec-defined default independently when unset or empty
-%% -- so a Flatpak-aware `XDG_DATA_DIRS' (which typically adds
-%% `~/.local/share/flatpak/exports/share') is honored in place of the
-%% default rather than merged with it.
