fix(ci): build WASM before website build in Lighthouse CI

The postbuild script hashes public/wasm/gosqlx.wasm to stamp a
content-addressed cache key into the service worker. Lighthouse CI
was missing the Go + WASM build steps that website.yml already has,
so the binary was absent and the build crashed with ENOENT.

Added: Setup Go 1.26 → make build in wasm/ → copy binary to public/wasm/
Reverted the existsSync guard hack added in the previous commit.
Bumped timeout to 15m to accommodate the Go build.
