Create Shopping List (Gemini Flash + Todoist)

Target flow:

1. Input is either a photo or a recipe web search
2. Extract ingredients (Gemini Flash for photos; web_fetch text → Gemini for websites)
3. Pull current Todoist Shopping list
4. Compare using overlap + synonym mapping (kept conservative; only merge high-confidence equivalents like coriander↔cilantro, panko↔breadcrumbs)
5. Update Shopping (default: add only missing items; skip salt/pepper)

Use the bundled script to handle the photo → ingredients → Shopping update part.

It also automatically saves a markdown entry into recipes/ (your cookbook knowledge base) and appends to recipes/index.md.

For recipe-name → web search, do it confirm-first using web_search + web_fetch, then feed the ingredients into the same update logic (and save the recipe).
