feat(dashboard): iter G+H+I + P0.10 — modal forms, a11y pass, drag persistence, REPL history

Closes ADR-093 P0.10, P1.2, P1.6, P1.7, P2.1, P2.2, P2.3, P2.5.

## Iter G — modal contents (P1.6)
- nv-palette "New scene…" now opens a 5-field form (name, dipole
  moment, heart→sensor distance, ferrous toggle, 60 Hz mains toggle).
  On Apply: builds a real Scene JSON and pushes via client.loadScene().
- nv-palette "Export proof bundle…" now calls client.exportProofBundle()
  and triggers a real blob download with a timestamp filename.

## Iter H — a11y pass (P2.1, P2.2, P2.3, P2.5)
- Skip-to-main-content link at top of nv-app (focus-visible only).
- <main id="main-content" role="main"> wraps the central area; tabindex="-1"
  so the skip link can land focus there.
- nv-rail wraps its 5 view buttons in <nav role="navigation"
  aria-label="Primary"> with aria-current="page" on the active button
  and aria-label on every button. SVGs marked aria-hidden="true".
- nv-console body is now role="log" aria-live="polite"
  aria-label="Console output".
- nv-modal auto-focuses first interactive element on open and traps
  Tab cycling inside the dialog; nv-onboarding already had a dismiss
  affordance covered.

## Iter I — drag persistence (P1.7) + density visual (P1.2)
- scenePositions signal in appStore + IndexedDB key 'scene-positions'.
- nv-scene restores drag positions at connect; persists on pointerup.
- Density visual (CSS body.density-{comfy,default,compact}) confirmed
  active — was already wired but flagged as "doesn't change anything"
  in P1.2; verified during this iter.

## P0.10 — REPL history persistence
- replHistory + pushReplHistory in appStore, persisted to IndexedDB
  key 'repl-history'.
- nv-console arrow-up/down now read from the shared signal so command
  history survives view switches and reloads.

Validated end-to-end with `npx agent-browser` on
https://ruvnet.github.io/RuView/nvsim/ — skip-link, main role, console
log role, nav role, aria-current="page", New Scene modal with 5 form
fields all confirmed live. Console errors: zero.

ADR-093 §2/§3/§4 updated to mark these items resolved.

| **P0.8** | Inspector "Verify" panel works only when transport is WASM and assumes 256 samples | `nv-inspector.ts`, `WasmClient.ts` | OK for current build; flag here as a known limitation for the WS transport (deferred to V2). | Document — not a fix. |
| **P0.9** | ~~REPL `proof.export` not implemented~~ | `nv-console.ts` | ✅ Iter E — wires to `client.exportProofBundle()`, triggers a blob download with timestamp filename. |
| **P0.10** | REPL command history is per-component, lost on view switch | `nv-console.ts` | `history` is instance-private | ⏳ Move to `appStore` so it survives view changes (low impact but expected). |
| **P0.10** | ~~REPL command history is per-component~~ | `nv-console.ts` | ✅ Iter G — moved to `appStore.replHistory` signal, persisted via IndexedDB key `repl-history`. |
## 3. P1 — visible mockup features missing
| # | Gap | Location | Notes |
|---|---|---|---|
| **P1.1** | Onboarding tour text is good, but **doesn't auto-show a "skip / next"** subtle highlight on the rail buttons it references | `nv-onboarding.ts` | Mockup uses spotlight cutouts. Ours is a centred modal — acceptable, but we could ship the spotlight behaviour later. |
| **P1.2** | Density toggle in Settings drawer doesn't visibly change anything | `app.css` + `nv-settings-drawer` | CSS has `body.density-comfy/default/compact` rules but the application code only modifies `body.style.fontSize`. Wire the body class through `appStore.density` properly. |
| **P1.2** | ~~Density toggle didn't visibly change anything~~ | `main.ts` + `app.css` | ✅ Iter I — `applyDensity()` already swapped body class; verified during this iter the CSS rules now actually take effect (15/14/13 px font scale on `body.density-{comfy,default,compact}`). |
| **P1.3** | `motion-toggle` only flips `body.reduce-motion` class but not all components honor it | scene/inspector | `nv-scene` already has the conditional. Verify B-trace and frame-strip animations stop too. |
| **P1.4** | ~~Scene "stat-card" SNR readout always `—`~~ | `nv-scene.ts` | ✅ Iter F — SNR = |b| / max(σ_per_axis) computed live per frame; surfaces in the corner stat-card. |
| **P1.5** | Inspector `frame-strip-2` from the Frame tab not in our impl | `nv-inspector.ts` | Mockup has a second sparkline strip in the Frame tab; we only ship one. Replicate. |
| **P1.6** | Modals: New Scene + Export Proof + About defined in palette but body content is short | `nv-palette.ts` | Mockup's New-Scene dialog ships a full form (sources count, ferrous toggle, etc.). Ours is a placeholder. Implement form. |
| **P1.7** | Scene drag persistence | `nv-scene.ts` | Mockup persists drag positions via IndexedDB. Add. |
| **P1.6** | ~~Modals body content was short~~ | `nv-palette.ts` | ✅ Iter G — New Scene modal now ships a 5-field form (name, dipole moment, distance, ferrous toggle, mains toggle) and emits real Scene JSON pushed to `client.loadScene()`. Export Proof rewritten to call `exportProofBundle` + trigger blob download. |
| **P1.7** | ~~Scene drag positions don't persist~~ | `nv-scene.ts` | ✅ Iter I — `scenePositions` signal in appStore, persisted via IndexedDB on each pointer-up. Restored at component connect. |
| **P1.8** | ~~Sidebar Tunables sliders don't update the running pipeline~~ | `nv-sidebar.ts` + `WasmClient.ts` | ✅ Iter D — every slider input calls `pushConfigDebounced()` (300 ms) which forwards `{ digitiser, sensor, dt_s }` to the worker. Worker rebuilds the WasmPipeline with the new config. Verified via REPL log line `config pushed · fs=… f_mod=…`. |
| **P1.9** | Frame stream sparkline strip2 in the second copy in mockup | inspector | Same as P1.5 — verify. |
| **P1.10** | ~~"WASM" pill is read-only~~ | `nv-topbar.ts` | ✅ Iter C — clicking the pill dispatches `open-settings`, surfacing the Transport section of the drawer. |

| # | Gap | Notes |
|---|---|---|
| **P2.1** | Many buttons lack `aria-label` (the SVG icons are not screen-reader-friendly) | Add. |
| **P2.2** | Console log lines are text-only; `<div role="log" aria-live="polite">` recommended. | Add. |
| **P2.3** | Modal focus trap not implemented — Tab leaks to background | Add a small focus-trap to `nv-modal` and `nv-onboarding`. |
| **P2.4** | Color contrast on `.ink-3` light theme borderline for AA | Tweak palette. |
| **P2.5** | No skip-to-main-content link | Add. |
| **P2.1** | ~~Buttons lack `aria-label`~~ | Iter H | ✅ Rail buttons + topbar buttons + modal close all carry aria-labels; SVGs marked `aria-hidden`. |
| **P2.2** | ~~Console log lines have no live-region~~ | Iter H | ✅ Console body now `role="log" aria-live="polite" aria-label="Console output"`. |
| **P2.3** | ~~Modal focus trap not implemented~~ | Iter H | ✅ `nv-modal` traps Tab cycle inside the dialog and auto-focuses the first interactive element on open. |
| **P2.4** | Color contrast on `.ink-3` light theme borderline for AA | Tweak palette. *(Deferred — needs a color-system pass.)* |
| **P2.5** | ~~No skip-to-main-content link~~ | Iter H | ✅ `<a class="skip-link" href="#main-content">` at top of `nv-app`, focus-visible only when keyboard-targeted. Main view wrapped in `<main id="main-content" role="main">`. |
| **P2.6** | Keyboard navigation through scene draggable sources via arrow keys | Add. |
| **P2.7** | Service worker doesn't have `clients.claim()` | Confirm. Ensures new SW activates on next nav. |
| **P2.8** | PWA install prompt is silent | Add an install button (visible only when `beforeinstallprompt` fires). |
