I'd personally go with your option one (1), but, using proper
roofing felt as the underlay, rather than just plastic sheet.

Aye, or even one the more modern breathable membranes though for a
"shed" this is probably wasted.

The tiles can then be placed back on battens, which are also sealed
with liquid felt to the underlay felt to stop the weather getting
in,

You don't want to seal the horizontal battens to the felt or any water
that does get under will puddle at each batten and not run down and
out at the eaves.

But the battens shouldn't be perfectly horizontal. They should always slope
slightly, either all to one end, or to both ends from the middle. This is
always normal practice to stop anything from gathering at the top edge of
the battens.

The slight run is never noticeable through the tiling.
