Visage packs v1

SHA256-manifested packs for the Visage app; see PACKS.json

Corresponding source (GPL-3.0 — espeak-ng)

The voice pack (voice-piper-*) uses espeak-ng as a separately spawned binary (aggregation, not
linking) under GPL-3.0; LICENSE-espeak-ng.txt inside the pack carries the licence text.
Corresponding source for both espeak-ng builds this pack ships:

• Standalone espeak-ng CLI (from the Homebrew bottle, upstream tag 1.52.0):
  https://github.com/espeak-ng/espeak-ng/archive/refs/tags/1.52.0.tar.gz
• Piper's own internally-used espeak-ng (built from the rhasspy/espeak-ng fork's floating
  master branch — upstream's own piper-phonemize build never pinned a fixed commit for this,
  so no permanent upstream tag exists to link to instead): archived from that branch's observed
  HEAD commit 8593723f10cfd9befd50de447f14bf0a9d2a14a4 (as observed 2026-08-17) and published
  as this release's own asset, espeak-ng-source-8593723f10cf.zip (above).
