Forward-merge triggered by push to release/0.6 that creates a PR to keep main up-to-date. If this PR is unable to be immediately merged due to conflicts, it will remain open for the team to manually merge. See forward-merger docs for more info.

#### Overview

Provide one canonical, versioned setup and validation guide for the experimental Switchyard integration in NeMo Relay 0.6.0. The guide makes the external Decision API boundary explicit and presents the release-specific setup in one place.

- [x] I confirm this contribution is my own work, or I have the right to submit it under this project's license.
- [x] I searched existing issues and open pull requests, and this does not duplicate existing work.

#### Details

- Expand the existing Fern Switchyard overview with a plain-language introduction, architecture diagram, component ownership table, exact prerequisites, and sibling checkout layout.
- Add a copyable build and real-service E2E workflow pinned to Switchyard commit `8f9db9a6a47f848cdff1d262276ba25a8ae9cbc8`, including the expected weak/strong/strong routing sequence.
- Document the E2E ports, health checks, ATOF-informed routing behavior, configuration boundary, and common preflight or startup failures.
- Keep the configuration page as the exhaustive option reference while adding the NeMo Relay 0.6 external-service warning and versioned source links.
- Point the Switchyard crate and example READMEs to the canonical Fern guide.

Validation:

- `just docs`
- `just docs-linkcheck`
- Focused pre-commit checks for all four changed files, including external link validation
- All-files pre-commit checks with the three attribution generators skipped; all remaining hooks passed
- Pinned real-service E2E: `real Switchyard E2E passed: ['provider/weak', 'provider/strong', 'provider/strong']`
- Missing checkout, mismatched commit, Relay readiness timeout, and preserved-log failure paths

The all-files Rust attribution generator rewrites the release branch's checked-in `ATTRIBUTIONS-Rust.md` despite no Cargo or lockfile changes. That unrelated generated drift is excluded from this documentation-only PR.

Breaking changes: none.

#### Where should the reviewer start?

Start with `docs/configure-plugins/switchyard/about.mdx`, especially the NeMo Relay 0.6 architecture boundary, copyable compatibility workflow, and troubleshooting table. Then review the narrower cross-links in the configuration page and two READMEs.
