Update the Worker to consume the shared edge request pipeline, import esbuild's wasm module through Wrangler's CompiledWasm rule, and mirror Deno's response and cache behavior more closely. This commit also adds KV-safe cache key hashing, badge cache invalidation by bundle key, R2-backed file responses, and the .well-known assets needed for public API metadata. The goal is to make the Cloudflare deployment behave like the existing Deno endpoint without relying on runtime wasm compilation that workerd rejects. Pulling these pieces together keeps the Worker deployable while preserving observable API behavior for cached JSON, badges, bundle files, and static discovery routes.
