Summary

Stabilizza l’integrazione OpenAI/ChatGPT Subscription e aggiorna la selezione dei modelli.

• aggiunge discovery dinamica dei modelli OpenAI, con fallback locale GPT-5.6;
• rende il reasoning capability-aware;
• separa /model e /effort;
• rafforza refresh OAuth, streaming/replay SSE, error handling e diagnostica sicura;
• blocca redirect cross-origin per evitare l’inoltro di dati sensibili;
• preserva risultati di errore per tool call saltate dopo Ctrl-C;
• limita l’anteprima del diff durante overwrite di file grandi, evitando letture/allocation illimitate.

Validation

• go test -count=1 ./...
• go test -race -count=1 ./...
• go vet ./...
• build macOS, Linux e Windows
• gofmt e git diff --check

Remaining live validation

Richiede credenziali reali:

• sessioni ChatGPT Subscription consecutive con testo e tool use;
• refresh token e riavvio;
• /compact su Platform e Subscription;
• verifica catalogo Subscription senza client_version.

Reviewed locally on the head SHA (06a984d): gofmt/vet/build clean, go test -race ./... green, git diff --check clean, dependency policy still only the MCP SDK subtree. CI is green. Checked the GPT-5.6 catalog against OpenAI's model guidance (gpt-5.6 alias → Sol; efforts none…max) — the static fallback matches. The Ctrl-C skipped-tool-result fix and the bounded overwrite preview both look right and are regression-tested.

Merging as-is. Live Subscription checks (M10 acceptance list) remain open until real credentials are available. Thanks Claudio!
