Cline v3.81.0 adds GPT-5.5 support and memory diagnostics

Cline `v3.81.0` introduces GPT-5.5 model support, making the model accessible to OpenAI Codex subscription users within the extension.

The release also brings a set of improvements to `cline-core` memory diagnostics used by the extension runtime.
