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.
