Summary

Kill plans are tagged by kind. An orphan plan has no port names, so it can't be built with any.

-type KillPlan = { scope; names; targets; withRuns: boolean }
+type KillPlan = RangePlan | OrphanPlan
+type RangePlan  = { kind: "range";  scope; names; targets }
+type OrphanPlan = { kind: "orphan"; scope; targets }

 killRange (cli.ts)
-  killTrees(visiblePids(plan), plan.withRuns)
+  killTrees(visiblePids(plan), RangeKill.killsRuns(plan))   # range → true, orphan → false

Also:

• ListenerScan (mac): an lsof address listed before any p line gets pid: null instead of a fake pid 0.
• ProcessTree.killTree drops its unused platform param and reads process.platform.

Evidence

• Before: n*:21000\np42\nn*:21001 → { port: 21000, pid: 0 }; nothing tested which kills look for leeway-run parents.
  After: → { port: 21000, pid: null }; RangeKill.killsRuns tests: a range plan → true, orphan-port and orphans plans → false.
• pnpm verify: green (274 passed, 3 skipped). pnpm test:linux: not run locally (podman not on PATH), so it rests on CI.

Merge Danger

Door: two-way

Blast Radius: none

KillPlan is internal to the CLI. The leeway kill output is unchanged.
