This commit introduces a curated 2048-word Bangla wordlist for BIP39. The wordlist was generated from the Wiktionary dataset, strictly following BIP39 rules:
- Words are between 4 and 8 characters long.
- First 4 characters uniquely identify the word.
- Excluded complex characters (e.g. 'রেফ', 'খন্ড ত') and complex conjunctions for ease of typing on phonetic keyboards.
