End-to-end voice clone: fetch_audio.sh → audio_to_manifest →
pick_context.sh → examples/generate. Caches each step by URL hash so
re-runs with the same --workdir skip the slow fetch and
diarize/transcribe stages.
Smoke-tested with cached fetch + manifest. Picks the highest-scoring
context clip across all (manifest, speaker) groups, hands it plus the
target text to generate via the new repeatable --context-wav /
--context-text pairs.
