chore: bump playground main-entrypoint chunk-size limit to 1960 KB

Replacing the parity base/root artifacts with the single variable-size
InboxParity ladder (64/256/1024) grew the playground main entrypoint to
1936.74 KB on CI, just over the 1925 KB hard limit. Bump with headroom,
following the existing bump-log pattern in vite.config.ts.
