PR 11 of a stack splitting #3026 into reviewable pieces. Builds and passes tests on its own; the command is fully functional only once the whole stack lands. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

What does this PR do?
Implements standalone EC2 node eviction: cordon, drain and terminate the instances.
Motivation
PR #3026 is too large to review as a single change. This is part 11 of 12 of a stack that splits it into small, individually-reviewable pieces that each build and pass tests on their own. See #3026 for the full feature context and end-to-end QA.
Additional Notes
Stacked PR — the base branch is
lenaic/CASCL-1386-evict-10-asg, notmain, so the diff shows only this step's change. Implements logic that earlier stack parts left stubbed withpanic("TODO …"). The code is taken verbatim from #3026 (rebased ontomain); there are no logic changes versus #3026.Minimum Agent Versions
