Add Breathing Exercise Feature to TalkHeal

[SharanyaAchanta]

Hi mentors 👋,

I'd like to contribute an enhancement to this project by adding a breathing exercise feature. This would include a calming animated circle to guide users through inhale-exhale cycles, and an optional timer.

This simple addition promotes mental wellness and aligns well with the feel-good theme of the section.

Please let me know if I can go ahead with this. I'd be happy to raise a PR soon. 😊
