Subject: [PATCH] remove(seekbar): drop realtime_waveform style
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Downloaded and fully decoded the entire audio file on every track
change — too CPU/bandwidth intensive to keep. Removes SeekbarStyle
variant, Rust command, waveform_decode function, all frontend canvas
code, seekbarRealtime_waveform i18n keys across all 8 locales, and
unused urlencoding dependency from Cargo.toml.
