feat: deploy docs via Zephyr Cloud with PR preview environments

[Copilot]

Replaces GitHub Pages with Zephyr Cloud for docs deployment and adds automatic PR preview environments.

Changes

• packages/docs/package.json — add zephyr-rspress-plugin ^0.0.59
• packages/docs/rspress.config.ts — register withZephyr() as first plugin; handles CDN upload during rspress build
• .github/workflows/ci.yml — drop GitHub Pages permissions + deploy steps; pass ZE_SERVER_TOKEN secret to docs build
• .github/workflows/preview-environments.yml (new) — builds docs on every PR and runs zephyr-preview-environment-action to post preview URLs as PR comments; skips build on closed events (cleanup only)

Required secret

Add ZE_SERVER_TOKEN (Zephyr org-level server token) to Settings → Secrets → Actions before merging.

For the deployment process to work, you will need to add ZE_CI_TOKEN to the list of turbo.json environment variables to pass on to the execution layer.

Both addressed in the latest commit:
