fix(plugin-multiplayer-sync): use pluginAPI.setTimeout for minimum_wait

[jodeleeuw]

Summary

Routes the minimum_wait delay in holdMinimumWait() through this.jsPsych.pluginAPI.setTimeout() instead of a raw setTimeout, so the pending timeout is registered with jsPsych and cleaned up automatically if the trial or experiment is aborted mid-wait. This matches the convention used by the core plugins (e.g. plugin-html-keyboard-response).

The spec's MockApi (which stands in for pluginAPI in the direct-trial() tests) gains a matching setTimeout helper that delegates to the real timer. Includes a patch changeset.

This ports the same fix that briefly landed on jspsych/jsPsych#3694 before the plugin was removed from that PR in favor of this repo (commit 5512c5b5 there).

Heads-up (out of scope here)

While porting this I noticed src/index.ts still reads the multiplayer API off this.jsPsych.pluginAPI ("flattened onto pluginAPI by jsPsych core", src/index.ts:111–113). jsPsych#3694 has since moved the API to a top-level jsPsych.multiplayer namespace, so this plugin will need a follow-up to read from jsPsych.multiplayer once that PR merges.

Test plan

• npx jest in packages/plugin-multiplayer-sync — 12/12 pass
• npx tsc --noEmit — clean

Closing as redundant: the identical fix landed on main via d7cccc7 (Hannah's independent port of the same jsPsych#3694 commit) and the #62 merge resolution, which also brought the correct Promise<void> typing. The changeset need is covered by #62's patch entry for plugin-multiplayer-sync.
