feat(mc): open files with their configured app via xdg-open

Browse Source 
Ship `mc.ext.ini` as the `local.mc.extIni` option (like `local.mc.menu`):
Enter browses archives in-place as before and delegates every other type to
`xdg-open`. Add public `mime.nix` with `xdg.mimeApps` defaults (pdf ->
zathura, images -> imv, audio/video -> mpv, office -> libreoffice) -- public
because those handlers are; personal browser/mail defaults stay private.

Also document, at the Hyprland swallow config, how swallowing differs from an
app opening fullscreen/maximized (LibreOffice restores its own maximized state
and looks swallowed but isn't).

Contents of mc's mc.ext.ini (file-type associations driving Enter/F3/F4).
The shipped baseline keeps mc's archive browsing and delegates every
other type to xdg-open, so the actual app is the XDG mimeapps default.
Like `menu`, it is a mkBefore definition: append a same-named section to
override one key (mc merges same-named sections, last key wins), or use
lib.mkForce to replace it entirely.
