ea382ec6a4 Tighten /start and /help copy
Less chatty, more precise. Explicitly mentions the /telegram:access
skill and the 6-char code format.

9a101ba34c Restrict bot commands to DMs (security)
- /status in a group would leak the sender's pending pairing code to
  other group members, who could then pair as that user
- Commands in non-allowlisted groups confirm bot presence and enable spam
- /start now acknowledges dmPolicy === 'disabled' instead of lying
- setMyCommands scoped to private chats so the / menu only shows in DMs
