Cline v4.1.4 Fixes Attachment Reset and API Key Errors

Cline v4.1.4 includes several fixes: reset pending attachments when starting a new task, so images from the previous task no longer carry over; surface a clear error when the selected provider has no API key configured; stop Claude 4.6+ and 5.x models being rejected with 'thinking.type.enabled is not supported' when they resolve from the offline catalog or from a hand-typed model id; send max_completion_tokens for reasoning models on OpenAI-compatible endpoints, and substitute image content for models without image support instead of failing the request; report the same provider failure once instead of twice in error telemetry, and rate-limit repeated failures from unattended retry loops.
