vh e0d1c44137 chore(fleet): repoint stale irv-ml1 refs (10.100.79.3 -> irv-ml1.nh3.internal)
The 2026-09-06 headscale cutover retired irv-ml1's wg0 tunnel IP 10.100.79.3
(now 10.6.110.50). Repointed all LIVE canonical refs to the DNS NAME so the next
move can't re-break them: homepage.href/siteMonitor labels across 25 stack
composes, load-bearing env defaults (asset-engine INFERENCE_HOST, open-webui
AUDIO_TTS_OPENAI_API_BASE_URL, skaldsong SKALDSONG_TTS_BASE_URL, zonos-gateway
ZONOS_URL, dia), homepage services.yaml manual cards (Voice Design Studio,
IRV-ML1), and servers/irv-ml1/ssh-target. Updated the stale 'WG tunnel' comment
to the mesh reality.

Left as-is: README curl-examples and .env.example comments (docs), and historical
mentions in CLAUDE.md/persistent-memory. NOTE: applying the label repoints to the
RUNNING irv-ml1 containers needs a recreate per service (labels read at creation);
deployed .env values are separate from these canonical defaults.

# Kokoro-82M served via remsky/Kokoro-FastAPI — the de-facto OpenAI-
# compatible wrapper for hexgrad's Kokoro-82M TTS.
#
# Why this stack exists alongside the other TTS:
# * Lowest-latency English in the fleet — ~300 ms TTFA on GPU,
# RTF 35-100x on a 4060 Ti class card.
# * Native streaming via OpenAI-compat `stream=true` over HTTP
# chunked transfer (Kokoro's KPipeline is a per-phrase generator).
# * Apache-2.0 weights + code; ~1 GB VRAM at fp16.
# * 60+ built-in voices (no cloning — for that use IndexTTS-2 or
# Chatterbox Turbo). Voices combinable via "voice(weight)+..." syntax.
#
# Image is a published GHCR build; no Dockerfile to maintain. Models
# baked into the image, no first-run download. Deploy is a pull + up.
#
# All tunables live in .env — edit that, not this file.

# Only request GPU runtime when running the GPU variant. Toggling
# `runtime: nvidia` from a YAML knob isn't possible directly; we
# accomplish it by routing nvidia-only fields through the
# NVIDIA_VISIBLE_DEVICES env var instead. The cpu variant ignores
# that env var harmlessly; the gpu variant honors it.

# Persistent custom voices: the wrapper only enumerates one voice
# directory (controlled by VOICES_DIR; default in-image is
# /app/api/src/voices/v1_0 which is NOT bind-mounted). We point it
# at /app/user_voices (which IS host-bind-mounted) and seed the
# built-ins into it on every container start. Custom voices written
# by scripts/blend_kokoro_voice.py land directly on the host bind
# mount and survive `up --force-recreate` and image upgrade.
# `cp -r` (no `-n`): always refresh built-ins from the image so
# upgrades that add/change built-in voicepacks propagate.
# Custom-named .pt files in user_voices that don't exist in v1_0
# are NOT touched (cp -r only copies entries from src).

# The image is python-based with curl available. /v1/audio/voices
