What's New

Adds correlation IDs to JSON receipts and fixes Codex session binding issues

New Features

JSON receipts now include `claude_session_id` and `claude_turn_uuid`
`session send-status --json` for Claude sessions now includes correlation IDs

Improvements

Session sends can be correlated without separate output queries
Improved timeout handling for `session send --wait` commands

Bug Fixes

Codex sessions correctly bind to sibling rollouts and maintain identity
`session send --wait` now honors the caller's `--timeout` argument
Long or multi-line follow-ups are now properly bound by `--wait`

Upgrade Notes

Scripts parsing JSON receipts should handle new `claude_session_id` and `claude_turn_uuid` fields. `session send --wait` timeout behavior is now consistent with caller settings.
