surajs-oai 137f25f643 Recover gRPC code-mode sessions after missing-session errors (#52235) ...

## Why

A host can reject a request for an unknown session while its lease streams remain open. Keeping that session binding prevents subsequent execution from recovering.

## What changed

Invalidate the session when `Execute` (including its response stream), `Wait`, or `Terminate` returns `NOT_FOUND`, allowing the next execution to open a fresh session. Return the failed call's error without replaying execution.

Document that these RPCs reserve `NOT_FOUND` for unknown sessions, while `CompleteToolCall` can use it for a missing invocation.

## Testing

Add regression coverage for recovery with lease streams still open, no replay of failed execution, and preservation of session state after `INVALID_ARGUMENT`. Add a cancellation-race test confirming that a late tool-completion `NOT_FOUND` leaves the session open.
