docs: propagate folder-naming convention + bump submodules for editor refresh

Convention:
* CLAUDE.md (root): new "Folder & File Layout (READ BEFORE CREATING NEW FILES)"
  section with required-name table and explicit legacy-drift list (mgc, vgc,
  dashboardapi).
* .claude/rules/node-architecture.md: file-naming convention + src/editor/
  module layout sections; serving recipe for /<nodeName>/editor/:file.

Submodule bumps:
* generalFunctions: shared output-format picker, redesigned position SVGs,
  tighter asset wizard, restored curve preview size.
* rotatingMachine: pump banner, circular state diagram, mode icon cards,
  picker integration, CLAUDE.md update.
* 10 others: per-node CLAUDE.md "Folder & File Layout" sections — 3 of
  them (machineGroupControl, valveGroupControl, dashboardAPI) carry inline
  warnings about their entry-filename drift.

 Each node follows a three-layer pattern:

 2. **Node adapter** (`src/nodeClass.js`) - bridges Node-RED API with domain logic, handles config loading, tick loops, events
 3. **Domain logic** (`src/specificClass.js`) - pure business logic, no Node-RED dependencies
 
+## Folder & File Layout (READ BEFORE CREATING NEW FILES)
+Every per-node file MUST use the folder name **exactly** (case-sensitive). No
+abbreviations. Quick reference:
+
+| Path | Required name |
+|---|---|
+| Entry file | `nodes/<nodeName>/<nodeName>.js` |
+| Editor HTML | `nodes/<nodeName>/<nodeName>.html` |
+| Node adapter | `nodes/<nodeName>/src/nodeClass.js` |
+| Domain logic | `nodes/<nodeName>/src/specificClass.js` |
+| Editor JS modules | `nodes/<nodeName>/src/editor/*.js` (extract when inline editor JS exceeds ~50 lines) |
+| Tests | `nodes/<nodeName>/test/{basic,integration,edge}/*.test.js` |
+| Example flows | `nodes/<nodeName>/examples/*.flow.json` |
