test(cmd): cover addAgentFlag + agentFromCmd helpers #69

	# PR + non-main-push gate. Runs the Go build + tests the release
	# pipeline depends on, so a broken main is caught before merge instead
	# of after.
	#
	# Scope intentionally narrower than `make regression`: `govulncheck` is
	# heavier and currently runs via `make regression` locally — adding it
	# here is a follow-up if/when it proves necessary as a merge gate.
