chore: clean up superproject structure

Move content to correct locations:
- AGENTS.md → .agents/AGENTS.md (with orchestrator reference update)
- third_party/docs/ (8 reference docs) → wiki/concepts/
- manuals/ (12 Node-RED docs) → wiki/manuals/

Delete 23 unreferenced one-off scripts from scripts/ (keeping 5 active).
Delete stale Dockerfile.e2e, docker-compose.e2e.yml, test/e2e/.
Remove empty third_party/ directory.

Root is now: README, CLAUDE.md, LICENSE, package.json, Makefile,
Dockerfile, docker-compose.yml, docker/, scripts/ (5), nodes/, wiki/,
plus dotfiles (.agents, .claude, .gitea).

+| `appIcon` | string | URL to square icon (192–512px) for PWA |
+| `includePagePath` | bool | Show page paths in side nav |
+| `navigationStyle` | string | `"default"`, `"fixed"`, `"icon"`, `"temporary"`, `"none"` |
+| `headerStyle` | string | `"default"` (scrolls), `"fixed"` (sticky), `"hidden"` |
+| `headerContent` | string | `"page"`, `"dashboard"`, `"both"`, `"none"` |
+
+---
+
+## `ui-page` — Dashboard Page
+
+| Property | Type | Notes |
+|----------|------|-------|
+| `name` | string | Displayed in nav and header |
+| `ui` | ref | Parent ui-base |
+| `path` | string | URL path segment, e.g. `/influent` |
+| `icon` | string | Material Design icon (no `mdi-` prefix) |
+| `theme` | ref | ui-theme reference |
+| `layout` | string | `"grid"`, `"fixed"`, `"notebook"`, `"tabs"` |
+| `order` | int | Position in navigation |
+| `breakpoints` | array | See breakpoints table |
+
+### Layout Types
+
+| Layout | Description |
+|--------|-------------|
+| `grid` | Responsive grid, widgets flow into columns |
+| `fixed` | Absolute positioned, no responsive reflow |
+| `notebook` | Single-column stacked groups |
+| `tabs` | Each group becomes a tab |
+
+### Default Breakpoints (grid/notebook/tabs)
+
+| Name | Min Width | Columns |
+|------|-----------|---------|
+| Mobile | 0 px | 3 |
+| Medium | 576 px | 6 |
+| Tablet | 768 px | 9 |
+| Desktop | 1024 px | 12 |
+
+---
+
+## `ui-group` — Widget Container
+
+| Property | Type | Notes |
+|----------|------|-------|
+| `name` | string | Group title (shown if `showTitle: true`) |
+| `page` | ref | Parent ui-page |
+| `width` | string/int | Column span (e.g. `"4"` = 4 of 12 columns) |
+| `height` | string/int | Minimum row height (`"1"` = auto-grow) |
+| `order` | int | Render order on page |
+| `showTitle` | bool | Show name as header |
+| `className` | string | Custom CSS class |
+| `groupType` | string | `"default"` (visible) or `"dialog"` (triggered) |
+
+### Sizing Rules
+
+- Group `width` sets column span out of page's total columns (default 12).
+- Group `height` is a **minimum** — group grows to fit content.
+- Widget `width` within a group is relative to the group's width.
+- Widget `height` is in row units (1 unit = theme's Row Height setting).

+
+| Property | Type | Default | Notes |

+| `colors.bgPage` | color | — | Page background |
+| `colors.groupBg` | color | — | Group background |
+| `colors.groupOutline` | color | — | Group border color |
+| `sizes.rowHeight` | string | `"default"` | `"default"` (48px), `"comfortable"` (36px), `"compact"` (32px) |
+| `sizes.pagePadding` | string | `"12px"` | CSS shorthand (e.g. `"12px 6px"`) |
+| `sizes.groupGap` | string | `"12px"` | Space between groups |
+| `sizes.groupBorderRadius` | string | `"4px"` | Group corner rounding |
+| `sizes.widgetGap` | string | `"12px"` | Space between widgets in group |

+
+## EVOLV Key Rules
+
+1. **12-column grid** with 4-col groups gives a clean 3-column layout at desktop.
+2. Set `height: "1"` on groups to let them auto-size (content determines height).
+3. Use `order` on groups to control left-to-right placement within a row.
+4. For compact dashboards: theme `rowHeight: "compact"`, `pagePadding: "6px"`, `groupGap: "6px"`, `widgetGap: "6px"`.
+5. Widget `order` within a group determines top-to-bottom flow (lower = higher).
+6. Gauge sizing guide: tank gauge `width:2, height:4` + 3/4 gauge `width:2, height:3` fits well in a 4-col group alongside a status text `width:4, height:1`.
