[Feature]: Add runnable Python examples / cookbook

[ihb2032]

Problem / Motivation

Zvec already has Python support, a one-minute example in the README, and Python snippets across the Quickstart and API/docs pages. However, it is still hard for Python users to find a small set of runnable, end-to-end examples for common workflows.

Right now, the documentation is strong for reference-style usage, but many users would benefit from example-oriented materials that they can copy, run, and adapt quickly. This is especially useful for users who are evaluating Zvec for the first time or trying to integrate it into a Python application.

A dedicated set of Python examples would help with:

• faster onboarding
• clearer understanding of recommended usage patterns
• easier local experimentation
• fewer repeated questions about how to combine schema creation, insert, query, filtering, update/delete, and optimization in real code

Thanks for opening this and for the thoughtful proposal. We agree that runnable, end-to-end Python examples can make onboarding much easier.

We do already have a Python notebook here https://zvec.org/downloads/walkthrough.zip Would that cover what you have in mind, or are there specific gaps you're still running into?

In particular, are you looking for a set of Python examples targeted at different use cases or workflows, such as RAG, image search, or codebase indexing? If so, it would be helpful to know which scenarios you think are most important so we can better understand what’s missing from the current notebook.
