v0.6.1 — Echo prompts and mobile scroll fix

A quick follow-up to the Echo release.

What changed

• Stopping combat during an active echo now asks for confirmation first, warning you that the echo will revert — no more throwing away a run with a stray tap.
• Dropdowns (the Witch’s affix picker, the Blacksmith’s tune list, and the rest) now commit on click rather than on first touch, so you can scroll through a long list on mobile without accidentally selecting the top entry.
