Restore user query history highlighting

Port the 0.130.x UserHistoryCell framing back onto the post-merge history-cell split so resumed and rewind-visible user prompts keep the highlighted User › label and divider rows.

Focused verification: cargo test -p codex-tui user_history_cell.

 - Preserve Open Codex fork behavior across the merge, including memory overlay/browser, rewind/revoke UX, persistent `Shift+Tab` speed toggle, `/btw`, `/effort`, subagent tracking, and git attribution.
 - Reconcile upstream ThreadSettings, `Op::UserInput`, MCP runtime environment, permission profile, rate-limit, status-surface, and package-layout changes with fork-specific runtime state.
 - Keep stale-turn output guards, foreground/background task state, and fork-correct package/update identity intact after the upstream merge.
+- Restore the 0.130.x user-query history highlighting with visible divider rows and the cyan `User ›` label after the upstream history-cell split.
 - Restore the Rust workspace release version so built binaries report `0.131.3` instead of upstream source-build `0.0.0`.
