Because you lack any reading comprehension, I'm going to explain this for you.
After Zelda found out that the only way to heal the sword was to infuse it with light for an incredibly long time, and that the wisdom stone turned anyone who swallowed it into a dragon, she opted to consume the stone.
The important thing to note is that when the user swallows the stone, they gain incredible power and get their wish, but lose their minds completely, instead falling back to their soul purpose or self mission which basically consumes them. We even see this with Ganon who transforms into the ultimate being and tries to kill Link immediately as his primal mind sees Link as a threat to his quest for power. A quest for power was Ganon's soul purpose and his wish.
Zelda, in this case, has an overwhelming urge to help and aid link and, in turn, save Hyrule, which manifests as her caring and imbuing the sword with her sacred light energy. This was her soul purpose and her wish.
>Supposedly Zelda loses her mind the moment she transforms yet Zelda actively communicates with Link telepathically throughout the game.
This is not the case. Whenever you hear Zelda saying "Find me" it's actually down to Zelda's final words as a human echoing through time. This happens several times, and she even repeats the "Find me, Link" line right as she transforms into a dragon. It's literally her words echoing through time.
>More importantly Zelda leaves a final tear for Link to access after he collects the other tears which implies cognitive capabilities of some sort, why else would she do this?
This is supposed to signify that Zelda is deep inside there still, somehow. Her residual sadness and emotions are stirred up again by the events of Tears of the Kingdom, and her subconscious leaks out. It's implied throughout the game that this "irreversible" dragon transformation may actually be reversible after all.
>mindlessly floating around
>actively assists Link in defeating Dragon Ganon
>So which is it?
It's her soul purpose again. You know, the one she takes on the moment she becomes a dragon. Her wishes to help aid link and save him are granted, but at the loss of herself and her being. She doesn't know WHY she's helping him, just that she must. As her soul purpose.
>They coordinate attacks midair with other sentient creatures? For a dumb animal Zelda sure knew that only Link could finish off Ganon with the master sword.
Her soul purpose. It was to aide and save Link, which in turn saves Hyrule.
