Summary

Default list commands now discover Claude and Codex together, with an agent discriminator on every session row and an AGENT column in combined human output. Existing Claude-only callers can retain their selection with --agent claude; --agent codex remains available.

Discovery results identify each requested agent as ok or error. Failed discovery returns ok=false and exit code 1 while retaining successful sessions, including over SSH and across multiple hosts. Missing Codex state is reported as an error; Codex listing still covers only the selected home and does not imply a running process.

Closes #75
