Use git-harness v0.3.1 for non-interactive network git (#19)

* Disable interactive git credential prompts on fetch operations.

Apply GIT_TERMINAL_PROMPT=0 to all network fetch paths so parallel git-rain
runs fail fast with a frozen auth message instead of interleaved TTY prompts.

* Use git-harness v0.3.1 for non-interactive network git and fix GoReleaser CI.

Delegate PrepareNetworkGit to git-harness instead of duplicating the helper,
pin github.com/git-fire/git-harness v0.3.1, and migrate stable releases from
deprecated brews to homebrew_casks so release config validation passes.

* Fix release gate to verify Homebrew cask publish path.

GoReleaser stable config publishes homebrew_casks under Casks/, so the
release workflow must wait on Casks/git-rain.rb instead of Formula/.
