ci(pages): fold GitHub Pages deploy into ci.yml (deploy-pages job, main-only)

Director chose fold-not-3rd-workflow. Added a deploy-pages job to ci.yml: needs build-and-test, runs only on push to main, builds site/ and deploys to GitHub Pages (job-level pages:write + id-token:write + github-pages environment). Removed the held scaffold pages.yml. Net: 2 root workflows (ci.yml + release.yml), honoring github-actions.md max-2. Pages already enabled (build_type=workflow); handbook + landing deploy to https://mcp-tool-shop-org.github.io/loadout-os/.
