fix: npm postinstall now extracts tar.gz archives for macOS/Linux

The release workflow uploads tar.gz archives (not bare binaries) for
macOS and Linux. The postinstall script now downloads the archive,
extracts the binary, and cleans up. This fixes `npx tokenusage` and
`bunx tokenusage` on non-Windows platforms.
