Sean Huang 09db085f94 Support negotiated server-side truncation in Code Mode clients (#58125) ...

## Why

Host-side truncation can bound Code Mode output before it crosses the transport, including script errors that would otherwise exceed the frame limit.

## What changed

- Negotiate server-side output truncation for stdio and gRPC sessions, with client-side fallback for older hosts.
- Forward output budgets for execution, waiting, and termination when server-side truncation is selected. Avoid truncating host-formatted output or appending script errors a second time.
- Preserve the negotiated mode across reconnects and reject hosts that cannot maintain it.

## Testing

Add transport and integration coverage for output budgets, oversized script errors, reconnect compatibility, and preservation of output-limit notices with a zero-token budget.
