docs(sightsound): NPU sight+sound runbook, fleet table, IOMMU/SVA root cause

frank-default-sightsound (FLM v1.0.1, XDNA2 NPU, port 52626) is live on
Dankclaw. Documents the first-deploy crash-loop root cause: iommu=off on the
kernel cmdline breaks the XDNA2 SVA bind (amdxdna_drm_open ret -19), so every
/dev/accel/accel0 open fails with ENODEV; fixed with iommu=pt + reboot.
Whole-registry single-port serving with per-request routing by exact FLM tag;
unknown tags fall back to llama3.2:1b (no 404). Health = GET /v1/version.
Vision + audio towers proven live (image_url color probe; audio control-pair
token-count probe). Updates AGENTS.md fleet table + runtime section, both
index pages, and the change log.
