fix(v3): promote Virtuoso to the first-class sidebar slot (was slopscale) (#554)

* fix(v3): promote Virtuoso to the first-class sidebar slot (was slopscale)

The bundled practice plugin was rebranded/re-homed from the SlopScale fork
(id: slopscale) to feedback-plugin-virtuoso (id: virtuoso); the desktop
bundle swap is feedBack-desktop#31. shell.js still promoted `slopscale`,
whose id no longer ships, so renderPromotedNav() (gated on the plugin
appearing in /api/plugins) would find no match: the dedicated sidebar slot
goes dark and Virtuoso drops to the generic Plugins gallery.

Swap the NAV entry + PROMOTED_PLUGINS slot slopscale -> virtuoso
(screen: plugin-virtuoso, label "Virtuoso - Practice", same FeedBarcade
anchor + target icon) so the practice plugin keeps its first-class entry.
Same pattern as the editor promotion (#546). Must land with the bundle swap
or the practice plugin regresses in the UI.

* fix(v3): clear dead slopscale id from Plugins gallery + refresh docs

Review follow-up (topkoa) — same dead-id bug class on a second surface:
- static/v3/plugins-page.js: drop the now-dead `slopscale: 'game'` from the
  CURATED category map and add `virtuoso: 'practice'`. The Virtuoso manifest
  sets `category: "practice"` (authoritative in categoryOf), so it already
  lands on the practice board; the curated entry is a defensive fallback so a
  manifest without `category` wouldn't drop to 'other'.
- README.md: SlopScale row -> Virtuoso (new repo URL + description + clone).
- docs/plugin-capability-inventory.md: slopscale row -> virtuoso (Active).

No behavior change beyond gallery categorization for the dead id.

CHANGELOG.md

@@ -35,6 +35,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - **Screensaver no longer kicks in during windowed-mode playback** (#686). While a song is playing, `static/app.js` now holds a [Screen Wake Lock](https://developer.mozilla.org/en-US/docs/Web/API/Screen_Wake_Lock_API) (`navigator.wakeLock.request('screen')`) so the OS display/screensaver stays awake even though only audio + the highway animation are active and the keyboard/mouse are idle. The lock is acquired on `song:play`/`song:resume` and released on `song:pause`/`song:ended`/`song:stop` (kept only while actually playing), and re-acquired on `visibilitychange` when the tab refocuses (the API auto-releases a lock whenever the page is hidden). Both the HTML5 `<audio>` and JUCE desktop playback paths emit the same `song:*` events, so the fix covers both. In slopsmith-desktop (Electron), where `navigator.wakeLock` is unreliable, it also drives a native `powerSaveBlocker` bridge via the optional `window.slopsmithDesktop.power.setScreenAwake` hook when present; both calls degrade silently where unsupported. Note: the browser Wake Lock API is secure-context only, so in a plain browser this is active on `localhost` / HTTPS only — a session opened over plain HTTP to a LAN IP (e.g. `http://192.168.1.100:8000`) won't keep the screen awake; front it with HTTPS or use the desktop app (see README → reverse-proxy notes).
 
 ### Changed
+- **Practice plugin first-class sidebar slot now points at Virtuoso.** The bundled practice plugin was rebranded/re-homed from the SlopScale fork (`id: slopscale`) to `got-feedback/feedback-plugin-virtuoso` (`id: virtuoso`); the desktop bundle swap is feedBack-desktop#31. `static/v3/shell.js` still promoted `slopscale`, whose id no longer ships — so `renderPromotedNav()` (gated on the plugin appearing in `/api/plugins`) would have found no match and the dedicated sidebar slot would have gone dark, dropping Virtuoso to the generic Plugins gallery. Update the NAV entry + `PROMOTED_PLUGINS` slot `slopscale` → `virtuoso` (`screen: plugin-virtuoso`, label "Virtuoso - Practice", same FeedBarcade anchor + `target` icon) so the practice plugin keeps its first-class entry. Also clear the now-dead `slopscale` id from the Plugins-gallery curated category map (`static/v3/plugins-page.js`) and add `virtuoso: 'practice'` as a defensive fallback (the manifest's `category: "practice"` is authoritative, so it lands on the practice board regardless), and refresh the stale SlopScale references in `README.md` + `docs/plugin-capability-inventory.md`. Must land with the bundle swap or the practice plugin regresses in the UI.
 - **3D highway: realistic curved metal frets.** The fret wires are now bowed `TubeGeometry` (the middle strings push away from the camera so the row of frets reads as wrapping a cylindrical neck — a depth cue) rendered with a lit `MeshStandardMaterial` instead of the old flat, straight `MeshBasicMaterial` boxes, so the scene's ambient + directional light glints across the rounded surface for a polished-steel look. The existing per-frame highlight is preserved unchanged: frets inside the active anchor still turn gold (`0xD8A636`), which under the metallic shading reads as brass. Metalness is kept moderate (0.4, not full-metal) because the scene has no envMap — a PBR full-metal surface would reflect black — with a dim emissive floor so frets stay legible down the fogged neck. Backported from the `highway_babylon` plugin's "hit-zone fret bars". All knobs (`FRET_BOW_DZ`, metalness/roughness/emissive) are tunable constants. `plugins/highway_3d` v3.25.0.
 - **3D highway: section + tone HUD cards now default OFF.** The v0.3.0 player chrome carries a persistent "Up Next" pill, making the in-canvas section card redundant by default (it doubled the readout, slopsmith feedback); the tone HUD follows the same less-is-more default. Both remain available in Settings → 3D Highway (visibility/position/size unchanged); users who previously toggled either explicitly keep their stored preference — only the untouched default flips. `plugins/highway_3d` v3.24.1.
 - **Perf**: replace runtime Tailwind Play CDN with a prebuilt static stylesheet (`static/tailwind.min.css`). The Play CDN's runtime JIT scanned the DOM ~1.8x/sec on the main thread (~37 ms blocking spans), dropping ~26% of frames in long playback sessions with the 3D highway as default. Theme extensions (dark/accent/gold colors, Inter font) move to `tailwind.config.js`; regen via `bash scripts/build-tailwind.sh`. No runtime build step — the generated CSS is committed. Fixes slopsmith-desktop#110.
