Pre-existing bug exposed by slice 33: the contract test had two
filepath.Join(".", "actions.go") entries in its requiredSnippets map.
Go silently drops duplicate map keys (last entry wins), so the first
list — including the canonical ErrActionPlanDrift pin and the new
ErrResourceRemediationLocked pin from slice 33 — was never actually
running. The test reported PASS while pinning nothing it claimed to.
Merges both lists into a single actions.go entry so every snippet
runs. Also corrects ErrActionPlanDrift's expected alignment to the
single-space form gofmt produced when the var block grew the new
sentinel.
