feat: add scripts for fetching and training educational corpus
- Implemented `fetch_corpus.py` to scrape Chinese educational content from Wikipedia, covering subjects like Chinese, Math, English, Chemistry, Politics, History, Geography, Physics, and Biology. - Developed `fetch_corpus_incremental.py` for incremental fetching of missing entries, with automatic retries for rate limiting and support for resuming interrupted downloads. - Created `train_chat.py` for training a dialogue model, including corpus cleaning, vocabulary management, and staged training with adaptive learning rates.
