feat(editor): pump banner, circular state diagram, shared picker

Editor UI overhaul:
* Pump banner — SVG of a generic centrifugal pump (volute, impeller,
  motor stub, suction + discharge pipes) at the top for visual orientation.
* Sequence-timing: side-panel inputs hover-coupled to a circular FSM donut.
  Arc angle proportional to phase seconds; idle a small loop slice at the
  top, operational the dominant arc at the bottom. Protected phases mark
  warm-up / cool-down with text-style shield (VS-15) inheriting arc colour.
  Donut height measured at runtime against the side-panel column so the
  bounding box lines up with the row stack.
* Movement mode: dropdown replaced with two compact 94x86 icon cards
  (Static linear ramp, Dynamic sigmoid).
* Output formats: switched to the shared evolv-icon-picker pattern (now
  also auto-applied platform-wide by generalFunctions/menu/iconHelpers).
* CLAUDE.md: Folder & File Layout section per EVOLV convention.

+## Folder & File Layout
+
+Every per-node file MUST use the folder name (`rotatingMachine`) **exactly**, case-sensitive. Full rule: [`.claude/rules/node-architecture.md`](https://gitea.wbd-rd.nl/RnD/EVOLV/src/branch/development/.claude/rules/node-architecture.md) in the EVOLV superproject.

+| Editor HTML | `rotatingMachine.html` |
+| Node adapter | `src/nodeClass.js` |
+| Domain logic | `src/specificClass.js` |
