undef_26 a3e9c91ce0 chore: stabilize Playwright E2E runs (#2164)
#1351 made `styleStore` initialization asynchronous in
`componentDidMount`. `setStyle` currently treats `toolbar:link`
appearing as the signal that loading is complete, but if the style
network request (`empty-style.json` from jsdelivr) takes over ~1s, the
`toolbar:link` can appear while `styleStore` is still null (because the
request has not finished). Subsequent `saveStyle` calls in tests then
silently do nothing, causing test failures (3 in #2157, and often 20+ on
my machine).

Changes are:

1. Mock the default empty style to avoid slow network E2E failures.
2. Also cap Playwright workers at 4 to avoid overloading Chromium on
high-core machines.

Fixes #2158.
