Two Plex-port fixes (both in the Plex play/data path):
1. Progressive streaming — play starts in ~1s instead of ~10s. play_plex_audible
no longer downloads the whole file before play_data; it resolves only the
part URL (new additive qbz_plex::plex_resolve_part_url, no body GET) and feeds
it into the player's streaming source (play_streaming_dynamic) via a shared
feeder module (remote_stream.rs, extracted from the QConnect renderer's HTTP
feeder — both now share it). Bit-perfect preserved: the original /file bytes
are streamed (no transcode), device init derives from the decoded stream; the
protected audio backend is untouched. Cast/DLNA keep the whole-file path.
Falls back to whole-file play_data on a non-direct part / streaming-setup error.
2. Re-sync no longer wipes hydrated quality — the sync did plex_cache_clear()
(full wipe) BEFORE the per-section save_tracks, defeating save_tracks' COALESCE
hydration carry-over, so already-hydrated albums reverted to a bare FLAC badge
on every settings-open / background-refresh / section-toggle. Replaced the full
wipe with a new additive plex_cache_prune_sections(keep) that removes only the
DE-selected sections, keeping the selected sections (and their hydration);
save_tracks then re-applies its per-section carry-over.

Hydration:
- qbz-plex: additive plex_hydrate_album_quality(base, token, rating_keys) — per
key plex_get_track_metadata (batch 5, 5s/call timeout, skip failures) then the
COALESCE write-back plex_cache_update_track_quality; awaited before re-read.
- qbz-player/qbz-core: patch_plex_quality / patch_plex_queue_quality patch the
in-memory queue in place by rating_key (for the now-playing stamp).
- qbz-slint: album-open trigger (gated on DB-NULL, not a value heuristic) then
refresh of all badge surfaces — album-card grid (re-read aggregate + patch
every model + the raw filter source), album-detail header + rows, now-playing
stamp. Re-sync stays routed through plex_cache_save_tracks (carry-over).
Quality badge consistency (the four surfaces must agree — and pre-hydration
show the filetype, not nothing):
- One shared classifier crate::quality::badge(format, bit_depth, sample_rate) ->
(tier, detail, tooltip); the album card, album-detail header and track rows
all route through it (kills the per-surface duplication that produced
"96 kHz" vs "96000 kHz"). sample_rate normalized to kHz via a >=1000 guard so
Qobuz's already-kHz values are never re-divided (no "0.041 kHz").
- New "lossless" tier: an un-hydrated lossless file (FLAC/WAV/ALAC… with unknown
bit depth) shows a generic filetype badge ("FLAC") instead of an empty badge,
rendered in QualityBadge (compact chip) + QualityBadgeFull; upgrades to
"24-bit / 96 kHz" after hydration. Local/Qobuz/mp3 unchanged.

Both tabs were Plex-blind. Loader-level merge (no qbz-library change):
- qbz-plex: additive PlexCachedArtist + plex_cache_get_artists() (aggregates
the flat plex_cache_tracks by normalized artist) + plex_cache_count_tracks().
- Artists tab: fold Plex artists into the local set before merge_artists
(same-name local+Plex collapse, summed tracks); artist-detail album grid +
counts switch to the Plex-aware get_albums_metadata_page; portraits fall back
custom/Qobuz -> Plex thumb -> album cover, dispatched via spawn_local_or_plex_loads.
- Tracks tab: prepend the bounded Plex set (<=5000) once at offset 0; later
pages stay pure-local so the virtualized 16K-row LIMIT/OFFSET path is intact.
- Tracks badge now includes the Plex count (matches albums/artists badges).
- All gated on plex_settings enabled (Plex OFF = byte-for-byte local-only).
Plex track id namespaced into [2^40, 2^41) so it cannot collide with local
track ids (< 2^40) or ephemeral ids (>= 2^48) in the merged Tracks tab — the
string rating_key is preserved in file_path, so playback is unaffected.

Move the Plex LAN client, hand-rolled XML metadata parsing, and the
SQLite plex_cache.db logic out of src-tauri/src/plex/mod.rs into a new
qbz-plex core crate so it can be shared by every frontend (Tauri, Slint,
TUI) per ADR-006. Plex previously lived entirely in src-tauri (~1715
lines), which blocked the Slint Local Library port from shipping Plex.
The extraction is mechanical: the module was already almost entirely
plain Rust (reqwest + rusqlite + serde + hand-rolled XML). The only
Tauri coupling was a dead plex_play_track command bound to AppState
(unreferenced; the live path is commands_v2::v2_plex_play_track, which
calls plex_resolve_track_media + AppState.player itself). That dead fn
and the vestigial #[tauri::command] attributes are dropped.
src-tauri/src/plex/mod.rs becomes a `pub use qbz_plex::*;` re-export so
every existing crate::plex::* call site compiles unchanged. Full Tauri
workspace cargo check stays green; qbz-plex tests pass.
