* fix(analysis): cap HTTP backfill on CPU-seed pipeline load Aggressive library analytics with multiple workers grew RAM unbounded: HTTP downloads finish in ~500 ms, but Symphonia decode + R128 loudness take seconds, so decoded `Vec<u8>` track buffers piled up in the CPU-seed queue while the HTTP worker kept fetching. On large libraries the process eventually saturated memory and forced the system into swap. Backpressure: the HTTP backfill worker now checks the CPU-seed pipeline depth (queued + running) against a `workers * 2` cap before popping the next job. High-priority (now-playing) jobs bypass the cap so playback prefetch is never starved. The CPU-seed worker pings the HTTP queue after every completed decode, so the gate releases the instant decode catches up. The frontend backfill loop already idles at its own watermark when the HTTP queue is satisfied — this change keeps the pipeline self-limiting end-to-end even when callers (library top-up, playlist enqueue) submit faster than decode drains. Tests cover cap scaling, the floor for workers=1, the idle decision, and the high-priority bypass. * docs(changelog): analytics aggressive scan no longer eats memory (#873)
