fix: OOV english words now transcribed via phonemize G2P + IPA

- Add phonemize (MIT) rule-based G2P as second fallback tier
- IPA phoneme -> katakana CV-syllable transcription table
- proposal -> プラポーザル, bilibili -> バイリーバイリー (no more letter-spelling)
- Letter spelling kept as last resort only
- Bridge logs SYNTH IN/OUT to stderr; tts.py drains stderr to Python logs
  so conversion results are visible in the server log
- Rebuild portable zip (83.8 MB)
