feat: migrate OG generation to takumi-js v2

Drop the @takumi-rs/* packages for takumi-js 2.0.0-beta.14. The umbrella
package selects its backend from `#backend` import conditions, so workerd
resolves to wasm on its own — removing the manual vite plugin, alias, and
optimizeDeps plumbing that forced the wasm runtime. As of beta.14
`@takumi-rs/wasm/auto` also ships a `workerd` export condition, so the
runtime-path alias is redundant.
