update Danish translation with 59 missing keys for the `resources.plugin` section as well as `message.startingInstantMix`, `resources.song.actions.instantMix`, `resources.song.fields.composer`, and `resources.plugin.name`.
Captured DevExternalScanner config value in the controller struct at
construction time instead of reading the global conf.Server pointer in
getScanner(). The background goroutine spawned by ScanFolders() was
reading conf.Server.DevExternalScanner concurrently with test cleanup
reassigning the conf.Server pointer, causing a data race detected by
the race detector in the E2E test suite.
* fix: split reflex -R flags to preserve directory exclusion optimization
Combining the _test.go exclusion pattern (which uses $) into the same -R
regex as the directory prefixes (^ui, ^data, ^db/migrations) disabled
reflex's ExcludePrefix optimization. Reflex disables prefix-based
directory skipping when the regex AST contains $, \z, or \b operators,
causing it to traverse into ui/node_modules and hit "too many open files".
Splitting into two separate -R flags fixes this: the directory prefix
regex remains $-free so ExcludePrefix works, while the _test.go pattern
gets its own flag where the $ anchor doesn't affect directory skipping.
* fix(gotaglib): pass filename hint to OpenStream for format detection
OpenStream relies on content-sniffing when no filename is provided,
which fails for some files (e.g. OPUS). Pass the filename via the new
WithFilename option so TagLib can use the file extension as a hint.
Also adds an OPUS test fixture and test entry.
