cards: fix links after workspace restructure

vat3-24k: publish milestone-3 full-VAT checkpoint (mixed verdict) + registry row

registry.json: machine-readable lineage/track/current manifest

docs: Current-trunk pointer + registry.json link

docs: training-pass column in registry index (phase labels as metadata, not names)

remove v1-ljspeech (renamed to baseline-ljspeech-22k)

docs: registry-index model card (multi-milestone scope; naming-change pointer)

rename: v1-ljspeech -> baseline-ljspeech-22k (registry naming convention; content identical)

derisk-energy-24k: replace pickle checkpoint with safetensors weights

derisk-energy-24k README: resolve stale open-questions section

Registry: mark both 24k promotions as published (owner call 2026-07-16)

derisk-energy-24k: LiteRT split-graph lane (spk + vat inputs, 24k vocoder)

Promote derisk_energy checkpoint_epoch=099 (staged, not pushed)

Promote HiFi-GAN 24k/80-band vocoder checkpoint g_02510000 (staged, not pushed)

docs: lowercase Reference/models in consumption steps (workspace convention)

docs: refresh model card (provenance, consumption) + ship engine config.json

feat: add LiteRT split-graph lane (litert-torch, mobile/delegate-ready)

feat: add weights-only-fp16 / f32-I/O artifact (mobile-recommended)

fix: re-export TFLite artifacts with corrected encoder LayerNorm
