cosskill update: Chinese version is live and the free tier now resets daily

Two more cosskill updates shipped this week:

- The Chinese-language interface is now fully live at https://cosskill.com/zh — the complete experience (personas, scenarios, pricing) works in Chinese alongside English.

- The free tier now resets daily: your first 3 messages need no account, and after signing in you get 10 messages a day. Every persona and scenario is included on the free tier.

cosskill (https://cosskill.com) is a browser-based AI communication simulator for rehearsing high-stakes conversations — salary negotiations, performance feedback, difficult personal talks — with realistic AI personas before they happen.

Pro ($12.90/mo, or $9.90/mo billed annually at $118.80/yr) removes the message cap and adds custom personas and history sync.
