P11.6 wiki regen + Phase 10 private-test rewrites where applicable

For all 11 nodes with auto-gen markers: wiki/Home.md sections 5 (topic
contract) and 9 (data model) regenerated via npm run wiki:all. New
Unit column shows '<measure> (default <unit>)' for declared topics,
'—' otherwise. Effect column now uses descriptor.description (P11.2
field) overriding the generic per-prefix fallback.

For rotatingMachine + reactor: Phase 10 test rewrites — 3 + 8 files
moved off private nodeClass internals (_attachInputHandler, _commands,
_pendingExtras, _registerChild, _tick, etc.) to the public
BaseNodeAdapter surface (node.handlers.input, node.source.*).
+6 / +7 net new tests.

+| Canonical topic | Aliases | Payload | Unit | Effect |
+|---|---|---|---|---|
+| `set.mode` | `setMode` | `string` | — | Switch the valve between auto / manual control modes. |
+| `cmd.startup` | _(none)_ | `any` | — | Initiate the valve startup sequence. |
+| `cmd.shutdown` | _(none)_ | `any` | — | Initiate the valve shutdown sequence. |
+| `cmd.estop` | `emergencystop`, `emergencyStop` | `any` | — | Trigger an emergency stop on the valve. |
+| `execSequence` | _(none)_ | `object` | — | Legacy umbrella that demuxes payload.action to startup / shutdown / estop. |
+| `set.position` | `execMovement` | `object` | — | Move the valve to a control-% position via execMovement. |
+| `data.flow` | `updateFlow` | `object` | — | Push a measured flow into the valve (variant + position + unit). |
+| `query.curve` | `showcurve` | `any` | — | Return the valve characteristic curve on the reply port. |
+| `child.register` | `registerChild` | `string` | — | Register a child measurement with this valve. |
