v0.2 polish: per-voice default speeds + trailing audio pad

- voicepacks.json: Asha 0.85, Vivek 0.9, Mukta 0.9, Dnyanesh 0.9
(matches v0.1 Asha/Vivek natural-pace docs; SPRINGLab voices
sound natural at the same range per listening tests)
- main.ts: 80 ms trailing pad after last chunk's audio so ISTFTNet
output's final phoneme release transient isn't clipped at buffer
edge — fixes "last word eaten" perception across all voicepacks
