Terminal UI stil, markdown tabele i prikaz troškova

- Dodat goldmark sa Table/Strikethrough/TaskList ekstenzijama (markdown.go)
- Prepisana CSS tema na konzolni stil (JetBrains Mono, tamna pozadina, prompt prefix)
- Prikaz troškova i trajanja posle svakog Claude odgovora (duration, cost, turns)
- Ispravljen parsing result eventa (json.RawMessage + top-level polja)
- Ispravljen concurrent write bug na WebSocket (write channel pattern)
