is there a way to play ffxiv on pc without buying game again?

I beg to differ, once you have an account and sub you can play anywhere. The only reason you've gotta buy the PS version is because there is No download. Honestly just google ffxiv client and play

Does the free version include a heavensward registration? Mine didn't.

No, the game requires the license for the version you are playing.

No way to transfer the PS4 lisence to PC, But it shouldn't be too costly to rebuy the game and expansion these days...
Only subscription time and collector's edition bonuses are shared between platforms.

Valkyrie_Lenneth is correct. Is it intuitive or sensible? No. But this is Square Enix we're talking about here. They're known for their arcane account and billing procedures and interfaces.
