* feat(mcp): add export_image_file tool — saves PNG/JPG/WEBP to disk
The existing export_image tool returns base64 inline, which MCP clients
display in chat but don't save to disk. This new tool writes the image
directly to a file path, making exports usable for documentation,
mockup reviews, and CI pipelines.
Parameters:
- path: absolute file path to save (required)
- ids: node IDs to export (optional, defaults to all top-level nodes)
- format: PNG | JPG | WEBP (default: PNG)
- scale: 0.1–4 (default: 2)

* feat(mcp): add export_image_file tool and fix headless PNG rendering
**New tool: `export_image_file`**
Saves rendered PNG/JPG/WEBP images directly to a file path on disk.
The existing `export_image` returns base64 inline — useful for chat
but doesn't produce files. AI agents and CI pipelines need actual files.
Path validation runs before the expensive render call. The tool
respects `fileRoot` restrictions.
**Fix: headless PNG rendering now matches the editor**
1. `computeAllLayouts()` called after `render` creates nodes via JSX.
2. Bundled Inter font loaded from disk — tries `../fonts/` (installed
package) then `../../public/` (project root). The web-based
`fetch('/Inter-Regular.ttf')` fails in Node.js.
3. Text measurement uses `renderer.measureTextNode()` — the same
ParagraphBuilder the renderer uses to draw text. Measurement and
rendering use the same SkiaRenderer instance, same fontProvider,
same font shaping. Zero hacks.
Export pipeline:
ensureInterFont() → SkiaRenderer + loadFonts() →
setTextMeasurer(renderer.measureTextNode) →
computeAllLayouts() → renderNodesToImage()
**Tests added** (6 new tests in mcp-server.test.ts):
- export_image_file produces valid PNG after render
- export_image_file without ids exports all page children
- export_image_file without document returns error
- export_image_file with out-of-root path returns error
- JPG and WEBP formats produce non-empty output
- export_image_file is listed in tools
* Remove .cue directory and revert .gitignore changes

* Move computeAllLayouts into renderTree, reuse exportImage in MCP
computeAllLayouts was in the render tool but renderJSX has multiple
callers (render, replace_node, automation server). Moving it into
renderTree ensures layout is always computed after JSX rendering.
export_image_file in MCP server was duplicating export_image logic.
Now delegates to exportImage.execute and just handles the file write.
