loop.detect() — four-strategy shootout on Drive Through Beat.wav + golden lock

One buffer, one entry point, four explicit strategies. The WAV is decoded with the package's own decodeWav (no browser resampling), then loop.detect(buffer, {strategy}) runs 'fast', 'precise', 'musical' and 'recurrence'. Each result is painted as a colored region on the shared waveform. The fast row is asserted against tools/goldens/loop_goldens.json (±441 samples, bpm ±0.1) — the same golden lock as examples/node/loop-detect.mjs (node-verified: Δ ≤ 1 sample on all four golden WAVs). Recurrence must report NO bpm field: it is tempo-free by contract and never invents one. Click a table row to audition that strategy's loop via LoopPlayer.
