Motori multipli: Codex e interruttore CLI nelle Impostazioni

Browse Source 
Introduce l'astrazione Engine (Claude Code, Codex) con argomenti e parser
propri e EngineRunner come unico punto di avvio, al posto di Claude.cs. Il
JSON delle chat salva motore e id di sessione (i file vecchi restano chat di
Claude Code). Cambiare CLI apre una nuova chat; modelli ed effort seguono il
motore; un motore non installato non è selezionabile. La CLI accetta
--engine <id>. Codex gira in sola lettura e la sessione si legge da
thread.started.
