v0.2.0

Implements Synod 0.2.

Added

• The player reads synod-scene/1 files and draws them on a canvas: circles, rounded rectangles, labels, lines and groups, with per-property keyframes, smootherstep easing, OKLab colour blending, group transforms, glow, and fit-and-letterbox on the Paper ground. It follows the reader rules in the Synod formats guide, and the same scene always draws the same frames.
• API: loadScene, compileScene, renderToContext (draw into any 2D context, for example an OffscreenCanvas for video export) and createPlayer. A player has play, pause, toggle, seek, setRate (0.25x to 4x), setLoop, setStopAtPause (Predict mode), nextFact, prevFact, factAt, timeOfSeq, setScene, resize, renderFrame(at) and destroy, and the events time, marker, fact, play, pause and scene.
• attachWebKitBridge posts player events to a WKWebView script message handler, and the IIFE build adds SynodPlayer.mount(selector, options) for Swift to call.
• Release assets: synod-player-<tag>.js (ES module), synod-player-<tag>.iife.js (global SynodPlayer), synod-player-<tag>.d.ts and SHA256SUMS. No runtime dependencies and no bundled fonts. Each bundle is at most 48 KB minified and 16 KB gzip (about 21 KB and 9 KB today).
• A demo page that loads a scene.json (file, drag and drop, ?scene=<url> or one of the bundled golden scenes) with transport controls, markers and a ?bench=1 timing overlay.
• Tests: display-list goldens for all 29 golden scenes and the hand-made fixtures, WebKit pixel goldens, a Chromium smoke test and a WebKit frame-time gate in CI.
• Performance, measured by npm run bench in Node with a no-op 2D context (so these are evaluate-and-draw call costs, not rasterisation): about 0.02 ms per frame for raft and webapp and 0.09 ms for the 50-node, 200-message stress scene, loading and compiling raft in about 7 ms, and no heap growth over 10,000 frames. Numbers in Safari on Apple silicon at 120 Hz are pending the owner's manual check and will be added here.
