test(cli): cover updater version and public client

[Vittuu]

Summary

• add updater, version, and public client coverage with hermetic tests
• add CLI seams needed to smoke version/help flows without depending on external state
• keep release/update behavior under test with focused path and transport checks

Why

This slice closes the lightweight public-surface gaps after the flow PRs: updater logic, version handling, and the exported pkg/goanime client. It is a good independent review unit and avoids the heavier scraper/player packages.

Validation

• go test ./internal/updater ./internal/version ./pkg/goanime -count=1
• go test ./internal/updater ./internal/version ./pkg/goanime -cover -count=1
• go build ./cmd/goanime
• go run ./cmd/goanime --version

Notes

• This remains draft while GitHub checks run.
