guinness-oai ca3246f77a [codex] Send realtime transcript deltas on handoff (#18761) ...

## Summary
- Track how many realtime transcript entries have already been attached
to a background-agent handoff.
- Attach only entries added since the previous handoff as
`<transcript_delta>` instead of resending the accumulated transcript
snapshot.
- Update the realtime integration test so the second delegation carries
only the second transcript delta.

## Validation
- `just fmt`
- `cargo test -p codex-api`
- `cargo test -p codex-core
inbound_handoff_request_sends_transcript_delta_after_each_handoff`
- `cargo build -p codex-cli -p codex-app-server`

## Manual testing
Built local debug binaries at:
- `codex-rs/target/debug/codex`
- `codex-rs/target/debug/codex-app-server`
