Presentation: Review lifehash.info for text & links

[ChristopherA]

@Sjlver Can you review https://lifehash.info for essential text and links that your site should have in common? In particular, it should have what this is and links back to the repo. Open to suggestions for the lifehash.info website as well.

Good point, added to the task list.

FWIW, there are a few correctness issues that I'd like to fix first before getting to the more "cosmetic" parts like links. For example, my WASM compilation toolchain currently does not support exceptions, and so seedtool.info silently fails in cases where seedtool-cli's C++ code throws one.
