Changes which were needed after the upgrade:
- Replace vite-plugin-virtual (vite 8 incompatible) with vite's
built-in `define` for the buildTimeConfig injection
- tsconfig: drop deprecated `baseUrl` (TS 5+ resolves `paths`
relative to tsconfig)
- Vitest 4: import `defineConfig` from `vitest/config` so `test`
is valid in vite configs
- Zod 4: rename `.errors` to `.issues`, make `ZodSchema` a
type-only import, drop the removed `SafeParseReturnType`
- Tighten/loosen generic casts in localStore to match stricter
zod 4 inference
- ESLint 9 `no-useless-assignment`: remove redundant initializers
and dead reassignments; disable the rule where Svelte's reactive
blocks confuse the analyser
- Svelte/eslint `prefer-svelte-reactivity`: disable for legacy
Svelte usages of URL / Set
- Misc naming-convention and prefer-const fixes
Deploys two workers: og-injector intercepts social crawler requests and
injects Open Graph meta tags; open-graph renders 1200×630 PNG cards
using Satori with repo/user avatars ported from avatar.ts.
