PR #2079 by teamsincetoday: Add 3 commerce intelligence patterns: affiliate extraction, video entities, monetization

• Added extract_affiliate_products pattern to surface both sponsored and organic affiliate opportunities from any video transcript, going beyond the existing extract_sponsors pattern.
• Added extract_video_commerce_entities pattern to identify all commercial entities in video content, categorized by type, timestamp position, and purchase likelihood.
• Added analyze_monetization_opportunities pattern to map audience intent to revenue strategies, covering affiliate links, sponsorships, and digital products.
• Registered all three new patterns in pattern_descriptions.json and pattern_extracts.json with appropriate metadata and tags.
• Integrated all three patterns into suggest_pattern under the ANALYSIS, BUSINESS, and EXTRACT categories, and documented them in pattern_explanations.md.

PR #2086 by majiayu000: fix: parse vendor prefix from model name for vendor/model convention

• Fix: Added fallback logic to parse the vendor prefix from a model name when no vendor is explicitly specified. When a model string such as ollama/llama3 is passed, the lookup no longer fails with a "could not find vendor" error; instead, the first path segment is split and checked against known vendors, correctly resolving the model to llama3 under the Ollama vendor group.
