Security:
- New internal/netguard package: podcast feed/enclosure fetching now
refuses to dial non-public IPs (loopback/RFC1918/link-local/cloud
metadata/CGNAT), validated per-connection including across redirects,
closing an SSRF gap where a malicious or compromised feed URL could
probe the server's internal network. Configurable via
VIBESONIC_PODCASTS_ALLOW_PRIVATE_NETWORKS for intentional LAN feeds.
- Podcast episode downloads capped at 4GB (was unbounded, disk-exhaustion risk)
- Cover art decoding now rejects images above a 40-megapixel budget
before full decode (decompression-bomb guard)
- HTTP server sets ReadHeaderTimeout (slowloris hardening)
- Admin folder-scan redirect now validated as same-site instead of
trusting the raw Referer header (open-redirect fix)
- Legacy Subsonic token/salt auth now uses a constant-time comparison
Web UI completion:
- Persistent player: shuffle and repeat (off/all/one) controls, wired
into queue advance/prev logic and persisted like other player state
- Admin user-permissions form: adminRole toggle (with a guard against
demoting the last remaining admin) and per-user music-folder access
checkboxes, backed by existing schema/enforcement that was previously
unreachable from the UI
- Playlist M3U8 import/export
Docs: added docs/client-compatibility.md (honest tracking template —
no client testing has been performed), docs/deployment.md,
docs/security.md, docs/backup.md; refreshed README and cross-links;
added a footnote in docs/subsonic-compatibility.md distinguishing
spec-standard from VibeSonic-original OpenSubsonic extensions.
Also added Go fuzz tests for the external-auth CIDR/IP parser and the
LRC lyrics parser.

Documents every currently-registered OpenSubsonic extension
(apiKeyAuthentication, formPost, getPodcastEpisode, songLyrics,
indexBasedQueue, playbackReport, topSongsByArtistId, transcodeOffset,
transcoding, sonicSimilarity), what backs each one, and what it's
tested against — cross-referencing the extensions-registry regression
guard that fails the build if an advertised extension's handler ever
goes missing. Also updates the getArtistInfo/getAlbumInfo/
getSimilarSongs rows and error-code list for Phase 3 changes.
