feat(release): ship darwin_amd64 and linux_arm64 binaries

Shared go-release-cgo.yaml runs each matrix entry natively (no cross-
compile), so adding platforms only needs two edits: a platforms input
in release.yaml and removal of ignore rules in .goreleaser.yaml.

New coverage:
- darwin_amd64 on macos-13 runner (Intel Mac)
- linux_arm64 on ubuntu-24.04-arm runner (ARM servers, Raspberry Pi,
  Apple Silicon via Docker/QEMU)

Kept: darwin_arm64, linux_amd64, windows_amd64.
Still skipped: windows_arm64 (uncommon, ARM Windows runner flakier).
