### PR [#2079](https://github.com/danielmiessler/Fabric/pull/2079) by [teamsincetoday](https://github.com/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](https://github.com/danielmiessler/Fabric/pull/2086) by [majiayu000](https://github.com/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.
