The fork_conversation RPC's availability checks were reworked to require two new gate functions and a direct bridge session ID check

What

  • The fork_conversation RPC's early bail-out conditions changed from four checks to three: it now checks two gate functions plus a freshly computed bridge session ID for being undefined, rather than relying on a separately tracked variable.
  • On top of the existing sdkUrl-based check, fork_conversation now returns "unsupported" if either of these two additional gate checks fails.

Why This tightens up when conversation forking is considered available, and adds conditions under which the RPC now reports itself unsupported instead of proceeding.
