Document the optional UIZZE preview endpoint

[samuelbushi]

What changed

The UIZZE plugin is already listed and works without an MCP server. This adds one factual sentence documenting the separate optional free preview endpoint for users who want a deterministic source check outside the Copilot plugin.

• Preview: https://uizze.com/mcp/preview
• Exposes exactly one check_ui_slop tool
• Anonymous; no account or token
• Not required by this plugin and does not change its local-only behavior

This corrects the handoff by describing the endpoint itself, rather than linking to plugin installation instructions.

All automated validation is green on this follow-up (plugin structure, README, build, line endings, codespell, risk scan, and duplicate check). The change is deliberately limited to documenting the separate preview endpoint; the Copilot plugin remains local-only and does not bundle or require MCP.

Distribution update: the maintained uizze/uizze@v1 GitHub Action tag and action.yml now match the current v1.2.11 release. The canonical repository description preserves the 800,000+ claim and names the GitHub Action and MCP tools.

Current public paths:

• Free Skill: https://uizze.com/ai-ui-slop
• No-account preview: https://uizze.com/mcp/preview
• Canonical map: https://github.com/uizze/uizze/blob/main/DISTRIBUTION.md

Correction to my earlier distribution comment: the current maintained release is v1.2.11, and both v1 and v1.2.11 point to the verified release commit. The current public paths are the free Skill at https://uizze.com/ai-ui-slop, the no-account preview at https://uizze.com/mcp/preview, and the canonical map at https://github.com/uizze/uizze/blob/main/DISTRIBUTION.md.

Fresh verification after the production release: the merged uizze/app fix now makes https://uizze.com/.well-known/agent-skills/anti-ui-slop/SKILL.md serve version: 1.2.11. Main CI, Cloudflare release verification, and production smoke checks all pass. This PR remains deliberately docs-only for the separate no-account preview endpoint; the Copilot Skill itself stays local-only.
