Native Codex hooks may identify a running session/group instead of the
rollout thread accepted by resume. Retain transcript paths, normalize the
thread identity, and share the parser with session discovery and probes.
Keep recovery paths when a matching provider acknowledgement omits them,
retain native identity metadata while reducing large SSH/WSL events, and
show the existing failure message when a saved target has no resume command.
Add regressions for Windows/guest paths and multiple CLI startup flows.
