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

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).

+# Default applications per file type -- the single source of truth for "open
+# with" across the desktop: xdg-open, file pickers, and Enter in mc (whose
+# mc.ext.ini delegates every non-archive type to xdg-open; see mc.nix).
+#
+# These belong in the public baseline because the handlers do too: zathura, imv
+# and mpv come from media.nix, libreoffice from home.nix. So "PDF opens in
+# zathura", "images in imv", etc. are the natural defaults of this baseline, not
+# personal choices -- every entry is mkDefault, so a consumer overrides one type
+# by setting the same key (their definition wins), or flips enable off entirely.
+#
+# Personal handlers -- web browser, mail -- are NOT here; they map to a specific
+# browser profile / mail client and live in the private inventory, merging into
+# the same defaultApplications attrset.
