Motivation
An initial step to adapt Bitcoin Core development for the AI era.
What this does
Introduces a single, low-noise entry point that points AI coding agents at the project's layout, build, test, coding-style, and contribution conventions, linking to the existing documentation (doc/developer-notes.md, doc/build-unix.md, CONTRIBUTING.md) rather than duplicating.
Notes
Documentation only; no code changes, so no accompanying unit or functional tests are applicable.
