v1.6.3

Added

• blog-to-video sample — new 22nd starter kit; fetches a blog post, plans 6 slides, generates DALL-E 3 images + OpenAI TTS narration, assembles and exports an MP4 via Canva
• video-generation sample — rewritten to use the same Canva pipeline (DALL-E 3 + TTS + Canva export); topic driven via --param topic=...

Fixed

• REST API adapter — body is now serialized as application/x-www-form-urlencoded when the connector's Content-Type header demands it; previously all POST/PUT/PATCH bodies were sent as JSON regardless
