* fix(native-chat): name a chat from its first message at once; the generated name replaces it
A native chat's one stored name was written only by a best-effort, one-shot
generation, so any failure left every surface on the 'Codex Chat' placeholder.
The first prompt now names the chat when its first turn starts, and the
generated name replaces it only while the field still holds that seed.
* fix(native-chat): the chat names setting says a chat shows its first message until it is named
* fix(native-chat): retry a failed first chat name twice before keeping the first message
A failed name generation was final for the chat's lifetime. The first name now
gets two retries, after 2 and 4 seconds, and stops early once the
first-message name was replaced.
* fix(native-chat): show a failed chat name on the tab hover card, with Regenerate name
A chat whose name generation failed after every retry gave no sign of it, and
nothing could run it again. The host now keeps the last failure in memory and
publishes it with the chat's status while the chat still has the name it failed
to replace; the tab hover card shows it with the error dialog, and a new
agentSession.regenerateName (behind a capability) makes one more try.
* fix: derive chat naming progress from host jobs
* fix(native-chat): merge duplicate import CI caught
* fix(native-chat): declare agentSession.regenerateName in the cross-version surface manifest
* fix(native-chat): stub naming-failure hook in SortableTab rename shortcut test
