Deivid Soto 5a92df1e14 feat(stream): HLS-copy — reemplazo resiliente del remux progresivo 
Nuevo modo VideoCopy en el engine HLS: ffmpeg -c:v copy (el vídeo jamás se
re-encodea — I/O puro, funciona en un NAS sin GPU), audio copy si ya es AAC
o AAC 192k si no, muxeado a segmentos fMP4 con ffmpeg escribiendo SU PROPIO
playlist (EVENT mientras corre, ENDLIST al acabar, EXTINF exactos en los
keyframes del source). Sustituye al remux growing-fMP4 servido por HTTP
Range artesanal, cuya fragilidad estructural produjo tres incidentes en un
día (init malformado/delay_moov, loop de re-seek por total inventado, iOS
rechazando total desconocido).

Diferencias deliberadas respecto al modo encode:
- playlist de ffmpeg servido desde disco (los cortes van a keyframe del
  source → duraciones imposibles de pre-renderizar; medido: probar
  keyframes antes cuesta 8-24s, inviable para TTFF)
- sin seek-restart ni auto-restart (la copia va a velocidad de disco y
  adelanta a cualquier viewer; el -ss de segmentos uniformes corrompería
  la timeline de cortes variables)
- sin caché HLS (regenerar no cuesta encode; cachear solo quema disco)
- resume vía -ss (snap a keyframe) + -output_ts_offset
- master playlist sin CODECS (un string hardcodeado equivocado hace que
  iOS rechace la variante; omitirlo es legal y universal)

Validación: TTFB seg-0 510ms sobre el MKV real del incidente (HEVC Main10
+ EAC3, 6.7GB). Suite de integración con ffmpeg real (tag smoke): h264+aac
(copy total), h264+ac3 (re-encode de audio con priming dts — la clase
delay_moov), hevc10+eac3 (la forma exacta del incidente, tag hvc1), resume
con StartSec, y serving del playlist; asserts de codecs vía ffprobe sobre
el playlist servido, suma EXTINF ≈ duración, segmentos completos en disco
(+temp_file = rename atómico).

El wiring web (plan remux→hls+videoCopy con gate de versión ≥1.0.10) va en
el repo web. Plan: docs/plans/hls-copy-remux-replacement.md (web).
