James c8a3e5fc4d fix(ci): unbreak format check on main + skip cli build:fonts when present
Two narrow fixes pulled out of a larger Windows-CI investigation:

## 1. Format check (`oxfmt`)

`packages/core/package.json` and `packages/shader-transitions/package.json`
had their `publishConfig` keys reordered to a non-canonical order by the
v0.6.1 release commit (`82fd2967`). Releases push directly to main without
going through PR CI, so the drift wasn't caught and `bun run format:check`
has been failing on every push since. Fix: re-run `oxfmt`.

## 2. `@hyperframes/cli` `build:fonts` skip-when-present

`packages/cli`'s `build:fonts` script regenerated
`packages/producer/src/services/fontData.generated.ts` unconditionally on
every cli build. The script reads `@fontsource/*` packages via
`require.resolve(...)`, which walks `packages/producer/node_modules/@fontsource/*`
junctions — these trip `EPERM: operation not permitted, stat` on Windows
GHA runners because of long-running bun-on-Windows workspace junction bugs
(see oven-sh/bun#23615, #18354, #10146).

`fontData.generated.ts` is committed to git, so the regeneration is only
needed when fonts actually change. Match the skip-when-present pattern
already in `@hyperframes/producer`'s own `build:fonts`. Doesn't fix the
Windows render verification end-to-end (the producer build itself still
trips junction issues — being tackled separately in #765), but at least
stops `cli build:fonts` from being its own failure point on Windows.

@hyperframes/core

Types, parsers, generators, compiler, linter, runtime, and frame adapters for the Hyperframes video framework.

Install

npm install @hyperframes/core

Most users don't need to install core directly — the CLI, producer, and studio packages depend on it internally.

What's inside

Module Description
Types TimelineElement, CompositionSpec, Asset, canvas dimensions, defaults
Parsers parseHtml — extract timeline elements from HTML; parseGsapScript — parse GSAP animations
Generators generateHyperframesHtml — produce valid Hyperframes HTML from a composition spec
Compiler compileTimingAttrs — resolve data-start / data-duration into absolute times
Linter lintHyperframeHtml — validate Hyperframes HTML (missing attributes, overlapping tracks, etc.)
Runtime IIFE script injected into the browser — manages seek, media playback, and the window.__hf protocol
Frame Adapters Pluggable animation drivers (GSAP, Lottie, CSS, or custom)

Frame Adapters

A frame adapter tells the engine how to seek your animation to a specific frame:

import { createGSAPFrameAdapter } from "@hyperframes/core";

const adapter = createGSAPFrameAdapter({
  getTimeline: () => gsap.timeline(),
  compositionId: "my-video",
});

Implement FrameAdapter for custom animation runtimes:

import type { FrameAdapter } from "@hyperframes/core";

const myAdapter: FrameAdapter = {
  id: "my-adapter",
  getDurationFrames: () => 300,
  seekFrame: (frame) => {
    /* seek your animation */
  },
};

Parsing and generating HTML

import { parseHtml, generateHyperframesHtml } from "@hyperframes/core";

const { elements, metadata } = parseHtml(htmlString);
const html = generateHyperframesHtml(spec);

Linting

import { lintHyperframeHtml } from "@hyperframes/core/lint";

const result = lintHyperframeHtml(htmlString);
// result.findings: { severity, message, elementId }[]
