feat: add native Android/Termux binary support (#887)

feat: added android support for running with termux

Adds GOOS=android arm64 build to goreleaser and platform detection in npm postinstall.

Tested by contributor on Termux where os.platform() returns 'android' and Linux binaries fail due to bionic vs glibc.
