feat(docs): adopt @conduction/docusaurus-preset + move to larpingapp.conduction.nl

[rubenvdlinde]

Summary

Adopts the shared @conduction/docusaurus-preset@^1.4.3 for the LarpingApp docs site and moves it to larpingapp.conduction.nl. Mirrors the openregister + mydash docs migrations (canonical example: ConductionNL/openregister#1444).

The docs site now inherits brand defaults (tokens, Navbar/Footer swizzles, KvK/BTW copyright, hex-watermark hero) and gets a brand-aligned landing page composed from <DetailHero> + <WidgetShelf>.

Changes

• docs/docusaurus.config.js rewritten to call createConfig() from @conduction/docusaurus-preset. Keeps larpingapp-specific bits: NL+EN i18n, mermaid theme, custom prism themes, Documentation+GitHub navbar items. Footer reduced to the brand "Conduction" column via baseFooterLinks().filter(...). minigames: false to drop the canal-footer mini-games on this product-doc surface.
• docs/package.json + docs/package-lock.json adds @conduction/docusaurus-preset@^1.4.3.
• docs/src/pages/index.js replaces the homepage with <DetailHero> (line-chart spike icon, orange accent, Install/Docs/GitHub CTAs) + a 3-card <WidgetShelf> (My character, Upcoming sessions, Recent scenes). Authored as .js not .mdx to avoid the docs-plugin/pages-plugin scan collision.
• docs/static/CNAME larpingapp.app to larpingapp.conduction.nl.
• .github/workflows/documentation.yml cname: updated to larpingapp.conduction.nl.

URL change

Production docs URL moves from https://larpingapp.app to https://larpingapp.conduction.nl. Old hardcoded larpingapp.app references remain in the top-level README.md (badge link, documentation link, directory comment) flagged for a follow-up sweep, not changed in this PR to keep the diff scoped.

Pre-existing MDX-3 issues excluded from build

Three feature-reference markdown files contain raw {token} patterns the Docusaurus 3.7 MDX parser interprets as JSX expressions ({type}_register, {characterName}_character_sheet.pdf, /characters/{uuid}):

• features/object-service.md
• features/pdf-export.md
• features/deep-link-registration.md

Rather than expanding scope, they are added to docs.exclude in the new config; an MDX-cleanup follow-up PR can re-include them once escaped.

Build outcome

• npm run build completes successfully against both locales (build/index.html and build/nl/index.html generated).
• Pre-existing preset warning about app-downloads.json (resolved at sites/www/ build time) is non-fatal and present in the canonical openregister + mydash builds.
• Footer-link warnings for /privacy /terms /iso are inherited from the brand preset defaults and resolve once those pages are added (or overridden) site-wide.

Test plan

• Confirm docs/build/index.html and docs/build/nl/index.html render correctly on local preview.
• Verify the larpingapp.conduction.nl DNS / GitHub Pages routing once a maintainer merges and the documentation workflow runs from the documentation branch.
• Open follow-up issue to clean up MDX-3 escaping in the 3 excluded feature markdown files.
• Open follow-up issue to sweep remaining larpingapp.app references in the top-level README.
