v0.3.1 — project site, hermetic tests, npm secret guard

What changed since v0.3.0

Added

• GitHub Pages project site — Dark Node themed landing page at pealmeida.github.io/anymodel-plugin with the Universal Node Cluster logo.
• CHANGELOG.md and a prepublishOnly npm hook.

Changed

• README redesigned with centered hero, logo, site badge, and a restructured quick-start section optimized for both human users and AI agents.
• Test suite is hermetic by default — 128 tests (125 pass, 3 live-fire tests opt-in via ANYMODEL_LIVE_TESTS=1). No test makes a live provider API call unless explicitly opted in.
• npm test runs bare node --test (portable across shells and Node 18/20/22).

Fixed

• plugins/.npmignore blocks local env/state files from the published tarball — .gitignore alone was insufficient inside files-whitelisted directories.

Removed

• Codex branding and the anymodel_ MCP tool prefix (tools are now bare delegate, review, …).
• Empty top-level scripts/ directory.

Corrected from the v0.3.0 notes

• MCP tools are named delegate, review, adversarial_review, status, result, cancel, models, setup — no anymodel_ prefix.
• Test suite: 128 tests (not 14).
