fix(ci): correct SEA binary build for cross-platform compilation

- Pass --platform and --arch flags to build script for target architecture
- Update cache path from single binary to dist/sea/ directory
- Fix binary name patterns in verify step (socket-win-*, socket-macos-*, socket-linux-*)
- Update artifact upload paths to match actual output locations

This fixes builds failing to create binaries for non-native architectures (e.g., arm64 on x64 runners).
