Besides heat, WD-40, and more leverage, the standard thing for removing rounded-out stuck bike bolts is to gently hammer in a slightly-too-large TORX bit which will bite (despite the damage), and unscrew.

You might damage the bit, but it's only a few euros spent - for a perfectly reliable technique.
