Switched from runtime file-based template loading (os.Stat + ParseGlob) to compile-time embedding (embed.FS + ParseFS). Templates are now bundled into the binary — no need to COPY them into Docker image. This fixes the fallback response issue where h.loaded was always false because templates weren't present in the container filesystem.
