## Why
Model pickers and session details show raw model IDs even when the catalog provides a display name.
## What changed
- Use catalog display names in model and reasoning pickers, session headers, status displays, and terminal titles, retaining fallback labels for models absent from the catalog.
- Keep model IDs for selection and persistence, and preserve picker highlights by ID when display names change or are shared by multiple models.
- Remove the legacy-model instruction from the full model picker.
## Testing
Add regression tests and snapshots for custom display names, startup and resumed session headers, fallback labels, terminal titles, and picker refreshes. Verify that selecting a display name still persists the original model ID.

## What changed
- Add `features.daemon_auto_start`, disabled by default and available through `/experimental`, to start the shared local server for eligible new, resumed, and forked sessions. Changes take effect on the next launch, and disabling the feature persists an explicit `false`.
- Require successful daemon startup and connection when auto-start applies. On failure, show guidance to rerun the same command with `--no-daemon` instead of silently falling back to an embedded server.
- Preserve embedded mode for excluded launches, including Bedrock sign-in, and carry exclusion warnings through resume and fork pickers. Honor `--no-daemon` without an exclusion warning.
- Update `/import` guidance to recommend restarting with `codex --no-daemon`.
## Testing
Add CLI and TUI coverage for automatic daemon attachment, startup and connection failures, `--no-daemon`, picker warning persistence, and Bedrock onboarding with and without a running daemon. Add snapshots and configuration-write assertions for the experimental toggle.
