feat: add mrpack export to edit instance tab
lets you export an instance as a .mrpack the same way the modrinth app does - pick which folders/files get included (defaults match modrinth: config/mods/resourcepacks/shaderpacks checked, rest unchecked), hash mods against modrinth so matched ones get referenced by url instead of bundled, everything else goes under overrides/. exported file lands in games/.../exports/ and opens the share sheet right after.
