fix(electron): pre-bundle lazy-route deps to avoid dev 504

Analysis pages (private/group chat) are lazy-loaded routes that pull in
heavy deps (echarts, markdown-it, snapdom, vue-virtual, etc.) which Vite's
cold-start scan does not discover. The first navigation triggered an
in-flight dependency re-optimization, invalidating already-loaded chunks
and failing with 504 (Outdated Optimize Dep) on the dynamically imported
page module. This surfaced after a fresh pnpm install wiped the warm
node_modules/.vite cache.

Add optimizeDeps.include so the initial optimize pass already contains
these deps, preventing mid-session re-optimization and the 504.
