The repository's own documentation describes the new arrangement

[sameera]

As a contributor to Nexus, I want the repository to say where components are authored and how to run them, so that I do not look for them at the path they used to occupy.

Acceptance Criteria

• Given the repository's contributor-facing documentation, when it is read, then it names the authored tree's location and states that .claude/ is not it.
• Given that documentation, when it is read, then it describes the maintainer's loop as pointing the install location at the checkout, with the commands to do so.
• Given README.md, CLAUDE.md and docs/, when each is searched for instructions that place or deploy Nexus components into this repository's .claude/, then there are none.
• Given a contributor follows the documented setup from a fresh clone, when they finish, then they can edit a component and see the edit take effect.

Notes

This story exists because the move is invisible in the diff to anyone who does not already know about it, and because the repository's own instructions are the first thing that goes stale when the arrangement they describe changes.
