v0.4.0 — Barcode, Discogs, PWA & a new look

Changed

• New brand — a beagle in headphones inside a retro TV over an open book, with the
  media(orange) hound(ink) wordmark. New icon everywhere (web favicon/apple-touch, macOS
  .icns, Windows .ico, README, wiki), brand palette (orange #E97B0C + ink #16232A) as the UI
  accent, and Fredoka as the brand/heading font. See docs/brand/.
• Decluttered UI — a two-row sticky header (brand/Help/Admin on top; media tabs + stats +
  Settings + Library below) that stays locked while scrolling, and the admin actions consolidated into
  popup menus: ➕ Add (photos/scan/CSV), 🔗 Connect (Discogs/Publish/Letterboxd),
  ⤓ Export (catalog CSV/JSON, changes, seen), 💾 Backup (backup/restore). Action rows wrap on
  narrow screens.
• Inline Help panel (❓) with searchable, collapsible sections; Settings dialog now scrolls and
  exposes the Library & data folder control.
• Desktop app slimmed 370 MB → 45 MB by using the native macOS WebKit backend (excluded Qt +
  unused scientific libs in the PyInstaller spec); the bundle version is stamped from the package.

Added — installable on your phone

• 📱 PWA — published catalogs are now an installable, offline Progressive Web App (manifest.json
  • a service worker). Add it to your phone's home screen for a full-screen, offline-capable app that
    auto-updates on every republish (the SW cache is stamped with the build content-version).

Added — the four design proposals (docs/design/)

• 📷 Barcode / UPC scanning — identify the exact release from the barcode instead of fuzzy OCR.
  Local decode via the optional mediahound[barcode] extra (zxing-cpp, a pip wheel, no system lib);
  music UPC → MusicBrainz/Discogs barcode search, movie UPC → UPCItemDB product name → the existing
  identify-by-title path. New 📷 Scan barcode admin tool (native BarcodeDetector camera + manual
  entry), POST /api/identify-barcode, and a barcode-first pass in mediahound build --online.
• 💿 Discogs integration — a Discogs music metadata provider ([music.metadata] provider = "discogs"),
  one-shot collection import (mediahound import-discogs <username>, a 💿 Discogs button, and
  POST /api/import-discogs), and condition-based price suggestions (resale.discogs_price).
  Token stored in the OS keychain (DISCOGS_TOKEN, in Settings → API keys).
• 🛟 Interop & safety — mediahound backup / restore (zip of RawImages + data + config; --no-photos
  for a quick curation-only backup; .env/secrets never included), a ⬇ Backup button + GET /api/backup,
  Letterboxd and JSON exporters (mediahound export --format letterboxd|json, plus a client-side
  🎬 Letterboxd button), and JSON Feed + RSS of recently-added items (data/feed.json / feed.xml,
  [feeds] config).
• ⭐ Personal catalog — per-item rating (★1–10), note, tags/shelves, and a lending tracker
  (loan out / returned, badge, On-loan filter), plus a 🎲 Surprise me picker and a My rating sort.
  All personal data is admin-only and stripped from the published catalog (bundle.js/collection.json),
  and corrections.json / loans.json are excluded from Publish. See PRIVACY.md.
• 📚 Library switcher — open / create / switch the served library at runtime from the admin UI,
  with no restart. Backed by a recents list (~/.config/mediahound/recent.json); GET /api/libraries,
  POST /api/switch-library, POST /api/create-library (all localhost-only). This is where the data
  directory is chosen — per library via config.toml [paths] — surfaced in the UI.

Fixed

• Upgrades now take effect — an existing library kept its own copy of the web UI, so upgrading
  MediaHound left the old interface in place. build/app-open now refreshes the app shell from the
  installed package (sync_web_assets), and the server sends no-cache on HTML/JS/CSS so a webview
  can't run stale code.
• hidden always wins — a class that set display (e.g. the static-copy banner) overrode the
  HTML hidden attribute, so JS couldn't hide it. Added a global [hidden] { display: none !important }.
• Static-copy guard — editing a static copy (no admin server) now shows a clear banner that changes
  live only in that browser, with one-click Export.
• Unidentified thumbnails — the mock/demo build generates real placeholder tiles, and identify.js
  falls back gracefully when a thumbnail file is missing (no more blank/broken images).
• CI: green again (fixed Ruff lint in test helpers) and GitHub Actions bumped to Node-24 majors.
