## Problem
The TUI resume/fork picker was backfilling thread names from local
rollout indexes. This was left over from before the TUI was moved to the
app server. It should be using app-server APIs because the TUI might be
connected to a remote connection.
This bug wasn't (yet) reported by a user. I found it by asking Codex to
review places in the TUI code where it was still directly accessing the
CODEX_HOME directory rather than going through app-server APIs.
## Solution
The resume picker and session lookups should use app-server thread APIs
only. Remove legacy rollout name/list backfills, and avoid local name
reads in fork history.
## Testing
I manually tested `codex resume` and `codex resume --all` to look for
functional or performance regressions in the resume picker.
