0.97.0

Added

• tg mcp with no profile serves every profile, on stdio and with --http (cli-core 0.450.0). An AI app needs one
  connector for Telegram, not one per profile. Each tool (tg_tools_search, tg_read, tg_write) takes a required
  profile (every profile here, no default) and the agent is told to ask when you did not name the account. The call
  runs in that profile's own tg <profile> mcp, started on first use and closed after 10 idle minutes, so each
  profile's permissions, session and audit log apply as before. tg mcp --revoke, tg mcp config and
  tg mcp server start|stop|status work without a profile too, with their own login. --public-url takes a path,
  https://<name>.ts.net/tg, so the tools share one tunnel address. The MCP Registry entry starts tg mcp.
  tg <profile> mcp is unchanged.

Changed — may break callers

• tg needs cli-base 0.63.0 (cli-core 0.450.0). Nothing tg uses changed in it.
