feat: improve model selection UX and fix queue/status behaviors

- Add search/filtering to the `/model` command with multi-word matching
- Finalize partial stream previews (e.g. thinking blocks) on turn abort instead of clearing them
- Dynamically format low-cost `$ value` metrics up to 5 decimal places in status outputs
- Update queue tests to expect text-turn plans for aborted turns with partial text
