Allay 6.1.0

Pairs with Allay Server 6.1, which keeps each player's consent; with an older backend Allay asks nobody, as before.

• ✅ Players agree before Allay answers. Before a player's first question, Allay says what it sends and keeps, where (allay.chat: the EU, under the GDPR and Spain's LOPDGDD; or the server's own backend), that AI providers write the answers, and that answers can be wrong, with [I agree], [No, thanks], and a link to the privacy policy. Nothing about the player reaches the backend before they agree; their question goes on once they do. The backend keeps the agreement, so a player is asked once per server. privacy.consent turns it off, privacy.policy_url links your own policy.
• ↩️ /allay privacy withdraw takes the agreement back: Allay stops answering and the player's agents stop. /allay privacy agree gives it without a question waiting. Erasing a player's data erases their agreement too, so they're asked again.
• 🇷🇺 Russian speaks to every player as «ты», the vanished-player line and /allay privacy included.
• 🔑 A license.key Allay couldn't read counts as soon as it can. A failed read was kept until the file changed, so a license put in place by another user stayed unread after chown. The log now says when the file can't be read.
