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.
