Cline CLI 3.0.49: checkpoints work again, restore is a full workspace rewind

Fixes a regression where the CLI never recorded checkpoints at all, and makes restore rewind the whole workspace instead of just the conversation. Also raises Ollama's response-start timeout to 5 minutes so cold-loading large local models no longer errors mid-load.
