Add Cookbook tab with 12 REST API examples

[jpelletier1]

• I have read and reviewed the documentation changes to the best of my ability.
• If the change is significant, I have run the documentation site locally and confirmed it renders as expected.

Summary of changes

Adds a new Cookbook navigation tab to the docs site, sourced from jpshackelford/oh-examples. The Cookbook is a collection of standalone, runnable Python examples that show how to use the OpenHands Cloud REST API.

What's added

docs.json — new "Cookbook" tab entry with 4 sidebar groups.

13 new pages under cookbook/:

Group	Pages
Landing page	cookbook/index.mdx — overview with CardGroup tiles, API overview table, and links to all examples
Sandboxes	start-sandbox — create a sandbox and run commands directly against the agent-server; clone-and-attach — provision a sandbox (clone + setup.sh) then attach a conversation
Conversations	conversation-metrics — CLI tool for cost/token usage (V0 + V1 auto-detect); conversation-tags — write/read key-value metadata on a conversation; per-conversation-secrets — inject secrets as bash env vars or MCP auth placeholders
Plugins & Skills	load-plugin — the plugins field that pre-loads a plugin at conversation-start; launch-plugin-badge — build no-code /launch links, HTML buttons, and README badges; upload-skills — upload a skills directory into a sandbox; test-mcp-config — validate MCP server configs via POST /api/mcp/test
Hooks	command-blacklist — PreToolUse hook blocking dangerous patterns; command-whitelist — PreToolUse hook allowing only an approved command list; workspace-isolation — enforce directory boundaries on both terminal and file_editor

Each page follows the doc style guide (frontmatter, code blocks, <Note> components, internal cross-links) and links back to the source files on GitHub.

@jpelletier1, thanks for this. It set the direction for the Cookbook tab, and I've put a new process in place to automatically generate these doc pages from OpenHands/enterprise-cookbook, where the examples now live. This way customers have a repo that they can clone and where we can run automated tests for the examples while the doc pages are automatically sync'd up when an example changes. I'd like to close this PR in favour of #884. Is that OK with you?

Once #884 merges we'll merge PRs on the OpenHands/enterprise-cookbook and the publication automation will update the doc site.
