Teleport-relay thinking-strip decision functions built but uncalled

Four new internal helper functions were added to decide whether to strip or mark 'thinking' content (Claude's intermediate reasoning output) after a "teleport relay" falls back to its standard path, and to log a cli_teleport_relay_thinking_settled event when that decision is made. Of these, only one function, which triggers the relay reverting to the standard path, is actually called anywhere in the current build; the three functions that would make the strip/mark decision and log the settle event are not called from anywhere.
