secantusdb.com goes live; geo cross-driver smoke tests
Two stories in v0.3.0a40. First, the secantusdb.com marketing site is live: a Pelican-built static site on S3 + CloudFront, sourced from website/ in this repo. Brandkit-themed, with a home page, a blog (these release notes), and CTAs out to the docs and PyPI.
Second, the geo work picks up cross-driver smoke tests: mongosh, the Node driver, and the Go driver each have a focused geo smoke suite that runs against a live SecantusDB daemon, on top of the existing pymongo conformance tests. If a wire-protocol detail of geo encoding breaks for any of those drivers, CI catches it. Plus a docs fix: the Sphinx sidebar logo now renders only once.
