Add a `README.md`

[srid]

Currently the README just symlinks to ETHIC. We want meta-level information, including "how to" adopt the ETHIC for one's own projects.

Presently, I do this:

: Retrieve v1 of https://ethics.codes/
wget https://raw.githubusercontent.com/EthicsCodes/hackers-ethic/refs/tags/v1.0.0/ETHIC

: Make GitHub consider our ETHIC as "code of conduct" on its UI
mkdir -p .github
(cd ./.github && ln -s ../ETHIC CODE_OF_CONDUCT.md && cd ..)

[nrdxp]

one issue is that I think the github page at https://ethics.codes is generated from the README.md symlink iirc
