v0.5.9

What's Changed

🚀 Features

• Music Discovery — more results & fresh picks on refresh: recommendations build from a larger candidate pool (more seeds, more similar/top tracks per seed) and return up to 60 tracks / 24 artists. The refresh button now rotates the listening window, shuffles seeds and uses score-weighted random sampling, so each refresh surfaces different — but still relevant — tracks instead of an identical list. (2e5311d)
• Admin-toggleable registration lock: enable/disable open registration at runtime, with a REGISTRATION_ENABLED env kill-switch that overrides the admin toggle. (34965b2)

🐛 Fixed

• Subsonic / Symfonium sync: omit null fields from JSON responses (Symfonium's strict parser aborted sync on null) + resolve pl- prefixed cover-art IDs. (7160786)
• Subsonic: drop file-based debug log spam, route through the logger only. (2a35daa)
• i18n: wire the recommendation/playlist UI to the app i18n system and fill locale gaps across en/pl/es/fr/de. (57f6227)
• Dev build: show a "Dev" badge in the sidebar footer next to the version. (94d4900)
• Dev environment: repair the Vite dev frontend — node-owned node_modules so the dependency optimizer can write its cache (was EACCES → blank page), BACKEND_URL=http://backend:8000 so the proxy reaches the backend, and allowedHosts so the dev server is reachable by hostname. (6ffe25b)

📦 Build

• Bump backend base image to the patched python:3.14-slim-bookworm digest. (a08dd6d)

🔧 CI

• Pin all third-party GitHub Actions to commit SHAs. (0883f13)
