The source website uses <span class='energy-text energy-text--type-fire'>
to render inline energy icons. BeautifulSoup's get_text() was stripping
these spans, losing the energy type information and causing merged text
like 'Discard aEnergy' instead of 'Discard a Fire Energy'.
Changes:
- Add ENERGY_TEXT_TYPES mapping for inline energy references
- Add replace_energy_text_spans() to convert spans to text before extraction
- Add extract_effect_text() helper with proper text joining (separator=' ')
- Update parse_attack(), parse_ability(), _parse_trainer_details() to use it
- Fix JSON encoding in convert_cards.py to use UTF-8 (ensure_ascii=False)
Before: 'Discard an Energy from this Pokémon'
After: 'Discard a Fire Energy from this Pokémon'
Re-scraped all 372 cards and regenerated 382 definitions.
