chore: update repo references after config -> tools rename

[btravers]

The repo was renamed btravstack/config → btravstack/tools to free @btravstack/config for the planned 12-factor env module (#1).

This updates every reference to the old name:

• root package.json: private package renamed @btravstack/config-root → @btravstack/tools-root, repository URL updated
• repository / homepage / bugs URLs in all six packages/*/package.json
• README title and reusable-workflow uses: examples
• usage comments in both reusable workflows

pnpm test and pnpm lint pass. Downstream repos using the reusable workflows keep working via GitHub's rename redirect; separate PRs update their uses: references.

Closes#1
