Two lint fixes on the DLNA test server, no behaviour change:
- nilerr: the "skip unreadable file, keep walking" branch in the
--media-dir WalkDir callback returns nil after a non-nil read error
by design; annotate it with //nolint:nilerr, matching the existing
skip-entry branch above it.
- revive (redefines-builtin-id): rename between()'s `close` parameter
(and `open` for symmetry) to closeTag/openTag so it no longer shadows
the builtin `close`.

--media-dir flattened all tracks into a single container named after --name, so
browsing showed one "<--name>" dir (and a doubled breadcrumb) instead of the
real album folder, and every track's artist was the hardcoded "Test Artist".
- Group tracks by their containing directory; each becomes its own browsable +
playable container titled after that directory (e.g. "Sunday at Devil Dirt").
- Derive the artist from the directory above the album
(<root>/<artist>/<album>/track), falling back to "Unknown Artist"; album stays
the track's own folder name.

Tooling to reproduce "album cover broken in the player" (disc #499) and to debug
STORED_MUSIC playback against a controllable DLNA source.
- dlnatest.Item gains ArtPayload/ArtMime; the Browse DIDL emits
<upnp:albumArtURI> and the art bytes are served at /AlbumArt/<id>.<ext>. The
built-in tracks carry a tiny PNG cover so the repro works with zero setup.
- audio + art are served via http.ServeContent (adds the byte-range support real
speakers use when streaming).
- example-dlna-server gains --media-dir: serve real .mp3/.wav/.flac/.m4a/.ogg
files, searched recursively so an artist/album tree works. Art per track: a
sibling <name>.jpg/.png, else cover.jpg/cover.png/folder.jpg in the album
folder. Files are read into memory (point it at an album, not a whole library).
- BrowseMetadata: serveContentDir now honours BrowseFlag and returns single-object
metadata (with the track's <res>). Speakers issue Browse(BrowseMetadata) to
resolve a track before playing; returning empty caused INVALID_SOURCE.
- fix SSDP discoverability on multi-interface hosts: join the multicast group on
the interface that owns the LAN IP (macOS lists lo0 first, so the old "first
multicast interface" join landed on loopback and never heard the LAN M-SEARCH).
- add an HTTP access log (method/path/status/bytes/peer, plus ObjectID+BrowseFlag
for Browse) so the speaker's request sequence is visible while debugging.

Adds a dependency-free Go DLNA/UPnP MediaServer used to develop and test
the upcoming "browse a DLNA server and play on a SoundTouch" feature
(https://github.com/gesellix/Bose-SoundTouch/discussions/213).
Two faces over one content core:
- pkg/dlna/dlnatest: an in-process server (httptest) serving rootDesc.xml
and ContentDirectory Browse for an injectable content tree, for fast
cross-platform unit tests with no Docker and no multicast.
- cmd/example-dlna-server: the same handlers behind a real http.Server
plus an SSDP responder (answers M-SEARCH, periodic NOTIFY), so a real
speaker on the LAN can discover it and fetch real (silent WAV) audio.
A Docker minidlna was unusable here: on macOS the container IP in the
DIDL <res> URL is unreachable from the LAN, and its SSDP never reaches the
speakers. A native Go server embeds the host LAN IP and is discoverable.
