[readme-publish-section-stale] [LOW] README Publish section: dead workflow link + wrong trigger

[thedavidmeister]

Dimension: 3 (documentation) · Severity: LOW

README.md:40-41 — the Publish section is wrong two ways:

1. It links .github/workflows/publish-soldeer.yaml ("Publish to Soldeer"), which does not exist. The actual release workflow is .github/workflows/package-release.yaml (name Package Release), delegating to rainix-autopublish.yaml@main.
2. It instructs "Tag v<x.y.z> on main", but the workflow triggers on push to main (on: push: branches: [main]), not on a tag. A contributor who follows the docs and tags a release sees nothing publish.

Proposed fix — correct both the link/name and the trigger description, e.g.:

Push to `main`. The
[`Package Release`](.github/workflows/package-release.yaml) workflow delegates
to rainix's reusable workflow, which derives the package name from the repo name
(`rain.math.binary` → `rain-math-binary`).
