Preact's `useContext` is exported, but `createContext` isn't

Description

apps/client/src/services/frontend_script_api_preact.ts

useContext is exported, but createContext isn't, which makes impossible to use React contexts or any libraries that depend on them.

Hi @melianmiko! I'm Dosu and I’m helping the Trilium team.

Looking at the frontend_script_api_preact.ts file, it appears that createContext should already be exported. The file uses a spread operator to export all hooks from preact/hooks (line 99), which includes both useContext and createContext.

Could you double-check how you're accessing it? The Preact API is exposed as a frozen object, so the import pattern might differ from standard React/Preact imports. If you're still not seeing createContext available, this could be a bug worth investigating further.

If it turns out createContext is indeed missing, there's a maintainer-approved process for requesting additional hooks: "If you find you are missing any React hooks (built-in or Trilium-made) during development, you can request them from the maintainers."

To reply, just mention @dosu.

Bruh, createContext isn't a hook, it's located in main preact module.

You're right, my mistake! Looking at the actual imports:

import { Fragment, h, VNode } from "preact";
import * as hooks from "preact/hooks";

Only Fragment, h, and VNode are imported from the main preact module. createContext is indeed part of the main preact module (not preact/hooks), and it's simply not imported or exported.

The fix would be straightforward - add createContext to the import from "preact" and include it in the preactAPI object.

To reply, just mention @dosu.
