fix: pre-cache ARMv7 Node.js binary to avoid cross-compilation

The ARMv7 build was failing because yao-pkg tried to compile Node.js
from source on an x64 runner, which lacks ARM cross-compilation tools.

Solution: Pre-download the official pre-built ARMv7 binary from
yao-pkg/pkg-fetch releases to ~/.pkg-cache before packaging. This
allows yao-pkg to skip compilation and use the cached binary directly.

Only affects ARMv7 builds - other platforms unchanged.
