Map OpenAI's context_length_exceeded errors (both the in-stream error events sent by the Responses API / ChatGPT Codex backend and HTTP 400 responses carrying the code) to LanguageModelCompletionError::PromptTooLarge. This stops pointless retries and surfaces the dedicated token-limit UI instead of a raw error string. Also record a synthetic request token usage when a completion fails with PromptTooLarge, so the context indicator reports Exceeded rather than the stale usage of the last successful request, and the next prompt qualifies for auto-compaction.
