Learn: add Tiger CLI and Tiger MCP overview

[atovpeko]

Describe your changes

Adds a Learn page introducing Tiger CLI and Tiger MCP: what each tool is, how they relate to the REST API, when to use which, and where they fit in your workflow. Continues the CLI/MCP docs work (umbrella #375) after the merged get-started (#383) and reference (#387) sections. Also backfills the /learn/tiger-cli-mcp cross-link into the five already-merged get-started and reference pages that point to it.

Affected pages

• /learn/tiger-cli-mcp

• 🧪 Component kitchen sink — check for visual regressions if you changed components, styles, or dependencies.
