M7: .fig export that opens and draws in other software

- The document and its pages now say they are visible and opaque, and a page carries its background opacity and enabled flag. Left out, a reader took them as hidden and drew nothing: every frame was blank and the page background transparent.
- The schema written into the file uses the format's own names, kinds (struct or message), field ids and enum values for everything the export writes. The schema text parser takes `NAME=n` and `type field=n`.
- Rectangles are written as rounded rectangles with their four radii. Frames, components, instances and sections carry their fill outline; plain strokes carry their stroke outline (a ring around boxes and whole ellipses, the widened path of other centred strokes).
- Text carries its layout settings and one line entry per paragraph. Font styles are written under their standard names ("SemiBold" becomes "Semi Bold", "Regular Italic" becomes "Italic"); the import reads both spellings as the same style.
- A line height that is a share of the font size is written as a raw multiplier: percent units count from the font's own line height, so 140 % was laid out taller than in FigCraft.
- Masks keep their type (alpha, outline, luminance), written and read back.
- The import reads per-side stroke weights whose zero sides are left out (a bottom-only border no longer comes back on all four sides).
- `meta.json` gives the page colour and the thumbnail size; archive members are in the usual order. Texture effects are written under the format's grain type; WebP export settings are written as PNG with a warning (the format has none).
- Docs: `docs/file-format-parity.md`, `docs/gaps.md` (gap 1), `ROADMAP.md`, `docs/target-app-parity.md` (wording only; no number moves).
