docs: refresh version pins and test counts to v2.2.0 (Batch 2)

Batch 2 of the documentation-accuracy audit (#53).

- F6 version pins:
  - GettingStarted.docc SPM snippet from: "1.0.0" -> "2.2.0" (from: "1.0.0"
    resolves < 2.0.0 and never reaches the 2.x format-aware APIs).
  - website BRIEF.md — "Latest release", the from: pin, the raw.githubusercontent
    image URLs, and the "verified against" snapshot all v0.8.0 -> v2.2.0 (date ->
    2026-07-21); dropped the now-stale "reflects the v0.8.0 snapshot / Linux real
    as of v0.11.0" caveat (Batch 1 already states multi-platform rendering as real).
  - (product.md Status was bumped to v2.2.0 in Batch 1.)
- F7 test counts: 374 -> 407 package tests on macOS (3 skipped); 356 -> 386 on
  Linux (1 skipped); "341 layout, 33 render" -> "353 layout, 42 render, 12
  MermaidKitC" — the previously-omitted third test target now counted.

Left as correct history: product.md's "G12 shipped in v1.4.0" (CHANGELOG 1.4.0).

Closes #53.

 | Rendering | Native geometry pipeline: parse → layout → common scene IR → draw. The layout core and scene IR are platform-free; each platform supplies only the draw surface (CoreGraphics, Silica/Cairo, Android/Skia `Canvas`, SkiaSharp, Flutter `Canvas`, or SVG/Canvas2D). No web view, no headless browser, no Mermaid.js. |
 | Dependencies | Zero third-party packages on Apple. On Linux the render backend adds Silica (Cairo/FontConfig); `MermaidLayout` depends on nothing. |
 | Coverage | **30 distinct diagram types** (`MermaidDiagram` enum, 30-branch parser dispatch, 30-row README matrix, 30 fixtures). |
-| Verification | 374 package tests on macOS, 0 failures (3 intentionally env-gated skips). On Linux, 356 tests run in a `swift:6.2` container (1 skipped) — the `MermaidLayout` suite plus Silica render smoke tests (all 30 fixtures render). |

 | Origin | Built so that a diagram's source of truth stays the Mermaid text — parsed, laid out, and drawn natively in a Swift app — with layout judged by machine-checkable geometry rather than pixels, and with no runtime dependency on a JavaScript engine or web view. Consumed by the Quoin markdown editor as a first-party engine. |

 | Dependency policy | The Silica/Cairo Linux render backend is behind the `LinuxRaster` package trait (default OFF). A `from:`-pinned consumer resolves a Silica-free graph on every platform — no unstable branch dependency, no Cairo/PureSwift stack fetched on Apple. Linux users opt in with `traits: ["LinuxRaster"]`. |
 | CI | `test` (macOS): `swift build` + `swift test` on Xcode 26, plus a compile-only iOS-Simulator guard (a UIKit branch with no test host that must always compile). `linux`: installs Cairo/FontConfig, then `swift build --traits LinuxRaster` + `swift test --traits LinuxRaster`, and a `swift build --target MermaidLayout` proving the default Silica-free graph builds. |
 | Parser honesty | `ParserHonestyTests` (41 tests) pins that syntax once silently dropped or mangled now parses faithfully; `AdversarialInputTests` (11) that hostile input never crashes. |
