nextra held at exact 4.6.0 until shuding/nextra #5034/#5036 ship a fix

[dickhardt]

nextra and nextra-theme-docs are pinned exact 4.6.0 (was ^4.6.0) on chore/deps-latest so npm install cannot drift onto 4.6.1.

4.6.1 moved to zod 4 stable. nextra-theme-docs's Layout destructures children out of props before LayoutPropsSchema.safeParse(themeConfig), while the schema still declares children: reactNode as required. Every page that goes through lib/nextra-layout.js fails prerender with Invalid input: expected nonoptional, received undefined → at children. Bisected: next 16.3.4 with nextra 4.6.0 builds; nextra 4.6.1 alone breaks it.

Upstream: shuding/nextra#5034 (closed without a release), #5036 and #5008 (open). No 4.6.2 exists; the next line is 5.0.0-alpha.24. Re-check when 4.6.2 or 5.0 ships and restore the caret.

Remaining npm audit item: @xmldom/xmldom 0.9.x (high) via speech-rule-engine ← mathjax ← nextra. Build-time only; nothing from it reaches the static export.
