* fix(loudness): target sync, -14 pre-analysis ref, queue UI, and reseed - Front: coalesce loudness refresh by target LUFS; replay-gain IPC dedupe keys include norm target and effective pre-attenuation so TGT changes apply. - Rust: placeholder gain before integrated LUFS uses pivot at -14 LUFS; UI gain from effective trim; reseed loudness after delete when waveform cache would skip. - Pre-analysis: store attenuation relative to -14 LUFS; engine and UI use an offset for other targets; migrate legacy absolute values on rehydrate. - Queue/Settings: Loudness/TGT labels vs value buttons; styles; i18n for help. * fix(i18n): simplify loudness pre-analysis helper copy Remove reference-target wording from loudness pre-analysis helper text and keep only the effective adjustment shown for the current LUFS target in all locales.
