rename: slopsmith → feedBack, byron → got-feedBack (#537)
* Update GitHub repo references from feedback* to feedBack*

* rename: slopsmith -> feedBack, byron -> got-feedBack

Renames across the entire codebase:
- slopsmith/Slopsmith/SLOPSMITH/SlopSmith -> feedBack/FeedBack/FEEDBACK/FeedBack
- byron/Byron/Byrongamatos -> got-feedBack/got-feedBack/got-feedBack
- /home/byron/ -> /opt/got-feedBack/
- byron@ougsoft.com -> hi@got-feedBack.org
- github.com/byrongamatos/ -> github.com/got-feedback/
- com.byron. -> com.got-feedback.
- SLOPSMITH_ env vars -> FEEDBACK_ with backward-compat fallback
- Protocol/storage strings migrated with read-old/write-new pattern
- window.slopsmith JS API -> window.feedBack (canonical) + backward-compat alias

Refs: #rename-slopsmith

* rename: complete regen against current main + fix backward-compat alias

Regenerated the slopsmith->feedBack / byron->got-feedBack rename on top of
current main (3 commits had landed since the branch: #572/#554/#574),
resolving the four content conflicts in favour of main's newer content
(autoplay/auto-exit, accuracy-badge, Virtuoso re-home, feedpak badge).

Completion fixes on top of the mechanical rename:
- Re-apply rename to post-branch content the original rename never saw:
  window.slopsmith(.Tour) consumers in lessons.js / notifications.js /
  onboarding-tour.js, and the matching JS + python tests (autoplay_exit,
  progression_*, test_feedpak_extension FEEDBACK_* env vars). The test env
  vars now match server.py (which reads FEEDBACK_SYNC_STARTUP /
  FEEDBACK_SKIP_STARTUP_TASKS), so the sync-startup test exercises the real
  path again.
- Restore the window.slopsmith backward-compat alias dropped during conflict
  resolution, and move the bus aliases to AFTER the _feedBackExisting merge
  block so they reference the fully-assembled object (also fixes the
  loop_api.test.js API-surface regex, which the original PR latently broke).
- Drop the stray empty data/web_library.db (runtime DB lives in CONFIG_DIR)
  and gitignore it.
- Fix stale tone-source test: feed[dB]ack -> fee[dB]ack to match shipped
  source labels.

Verified locally (org CI billing-blocked): JS 819/819 pass; pytest 1669
passed / 1683 collected with 0 import errors; zero residual slopsmith/byron
except the two intentional window.slopsmith aliases.

* rename: implement advertised backward-compat + prune dead community plugins

Address gaps where PR #537's "Backward compatibility" section was advertised
but not implemented, and clean up the community plugin list.

Env vars (FEEDBACK_* canonical, legacy SLOPSMITH_* honoured):
- New lib/env_compat.py (getenv_compat / env_flag_compat) + tests. server.py
  (_env_flag + all FEEDBACK_* reads), diagnostics_hardware, gp2midi and
  tailwind_rebuild now resolve the legacy alias, so existing SLOPSMITH_UI /
  SLOPSMITH_PLUGINS_DIR / etc. deployments keep working.
- Fix the rename collapsing plugins/__init__.py and minigames/routes.py from
  `FEEDBACK_PLUGINS_DIR or SLOPSMITH_PLUGINS_DIR` into a redundant
  `FEEDBACK_ or FEEDBACK_` (the fallback was silently lost).

Storage (app.js update-channel):
- Read feedBack-update-channel, fall back to legacy slopsmith-update-channel,
  and clear the legacy key on write — so a user's update-channel preference
  survives the rename instead of resetting to "stable".

Community plugin list (README): the rename rewrote third-party repo URLs we
don't own. Probed every one; their owners never renamed, so:
- Restore the 13 live community plugins to their real slopsmith-* names.
- Prune 6 that are 404 to the public (topkoa splitscreen/stems, OmikronApex
  tuner, Jafz2001 nam-rig-builder, DeathlySin song-preview, Erikcb91 shuffle).
- Fix a pre-existing Guitar Theory clone-command typo (nam-tone -> guitar-theory).

Verified: env_compat 7/7, JS 819/819, pytest 1690 collected / 0 import errors,
rename-sensitive + startup suites green.

# Plugin styling — the `styles` capability
> Building for the redesigned **v3 UI** (`FEEDBACK_UI=v3` / `/v3`)? v3 uses `fb-*`
> design tokens and a restructured player chrome with a dedicated plugin-control
> slot. See **[plugin-v3-ui.md](plugin-v3-ui.md)** for the player-chrome contract
> plugins must follow in v3.
FeedBack serves Tailwind as a **prebuilt** stylesheet
(`static/tailwind.min.css`), never the runtime Play CDN. The CDN's on-the-fly
JIT rescanned the DOM on the main thread and dropped ~26% of frames with the 3D
highway running (feedBack-desktop#110). See **constitution Principle II**.
A prebuilt stylesheet only contains the classes the build scanner saw in **core
source at core build time**. That has a consequence for plugins:
- Core's build scans bundled plugins on disk, but **a plugin installed at
runtime** (community / NAS) was never scanned. Its classes — especially
arbitrary values like `text-[11px]`, `grid-cols-[1fr_auto]`,
`shadow-[0_0_8px_rgba(0,0,0,.5)]` — are **absent** from the served CSS, so its
UI renders unstyled.
The `styles` capability fixes this: your plugin ships its **own** compiled
stylesheet and declares it in the manifest. The frontend injects one versioned
`<link rel="stylesheet">` into `<head>` when your plugin activates, covering both
your screen and your settings panel.
> You only need this if you use Tailwind classes that aren't guaranteed in core —
> in practice, **any arbitrary-value class** (`w-[37px]`), or a custom class core
> doesn't ship. If you use only common core utilities (`flex`, `p-4`,
> `text-gray-300`, `bg-dark-600`), you can omit `styles` and rely on core's CSS.
## 1. Declare it in `plugin.json`
```json
{
"id": "my_plugin",
"name": "My Plugin",
"version": "1.2.0",
"screen": "screen.html",
"script": "screen.js",
"styles": "assets/plugin.css"
}
```
`styles` is a **plugin-root-relative path that must live under `assets/`** (like
`screen`/`script`/`routes` are root-relative). It serves through the sandboxed
`/api/plugins/<id>/assets/...` route, so the file must be at
`<plugin>/assets/plugin.css`. The injected `<link>` is cache-busted with
`?v=<version>`, so **bump your manifest `version`** whenever you rebuild the CSS,
or browsers may serve a stale copy within a session.
## 2. Build the stylesheet — utilities only, `preflight: false`
Core already ships Tailwind's base reset (preflight) once. Your plugin must
**not** re-apply it, or it would double the reset and fight core's styles. Build
with `corePlugins: { preflight: false }` so your sheet emits **only the utility
classes your files use**.
`tailwind.config.js` (in your plugin repo):
```js
/** Plugin stylesheet build — utilities only, scanned from this plugin's files.
* Regenerate assets/plugin.css with: bash build-tailwind.sh */
module.exports = {
corePlugins: { preflight: false }, // core owns the single base reset
content: [
'./screen.js',
'./settings.html',
'./screen.html',
// add any other file that carries Tailwind classes (e.g. './tour.json')
],
theme: {
extend: {
// Re-declare any core theme tokens you reference so they compile here.
colors: {
dark: { 900: '#050508', 800: '#0a0a12', 700: '#10101e', 600: '#181830', 500: '#1e1e3a' },
accent: { DEFAULT: '#4080e0', light: '#60a0ff', dark: '#2060b0' },
gold: '#e8c040',
},
fontFamily: { display: ['"Inter"', 'system-ui', 'sans-serif'] },
},
},
// Mirror only the dynamically-built classes your code generates at runtime
// (Tailwind can't see them textually). Drop this if you have none.
safelist: [
{ pattern: /^(bg|text|border)-(dark|accent)(-.+)?$/ },
],
plugins: [],
};
```
Input CSS — **`@tailwind utilities;` only** (no `@tailwind base`, that's the
preflight you're disabling):
`_plugin.src.css`:
```css
@tailwind utilities;
```
Build script `build-tailwind.sh` (run at your plugin's release time — the output
is committed; end users never build):
```bash
#!/usr/bin/env bash
set -euo pipefail
cd "$(dirname "$0")"
# Pin the same Tailwind 3.x core uses so output stays diff-stable.
exec npx -y tailwindcss@3.4.19 \
-c tailwind.config.js \
-i _plugin.src.css \
-o assets/plugin.css \
--minify
```
```bash
bash build-tailwind.sh # writes assets/plugin.css — commit it
```
## 3. Rules (inherited from the constitution)
- **No Play CDN, no runtime CSS JIT** — anywhere, ever. Same rule that binds core.
- **`preflight: false`** — utilities only; core ships the one base reset.
- **`styles` under `assets/`** — it serves through the sandboxed asset route;
`..`, absolute paths, and NUL bytes are rejected by `safe_join`.
- **Bump `version` on every CSS rebuild** so the `?v=` cache-buster fetches fresh.
- Plugins without `styles` are unaffected and inject no `<link>`.
## How it works (for reference)
- The loader derives a manifest-only `has_styles` boolean and passes the `styles`
path through to `/api/plugins` — no plugin code is imported
(`plugins/__init__.py::_nav_entry`).
- The frontend (`static/app.js::_injectPluginStyles`) injects one
`<link rel="stylesheet" data-plugin-id data-plugin-version
href="/api/plugins/<id>/assets/plugin.css?v=<version>">` (the `styles` value —
e.g. `assets/plugin.css` — appended to `/api/plugins/<id>/`) into `<head>`, **before** the
screen markup so styles are present on first paint. It's deduped by version: a
plugin upgrade swaps the old `<link>` for the new one; re-activation never piles
up duplicates.
- The stylesheet is served by the existing
`/api/plugins/<id>/assets/<path>` route as `text/css`.
