Add zhtw - Taiwan Traditional Chinese converter

[rajatim]

Description

Add zhtw to the Simplified/Traditional Chinese Conversion tools list.

Why zhtw?

• Taiwan-specific: Unlike OpenCC which does generic S↔T conversion, zhtw focuses on Taiwan terminology (e.g., 软件→軟體 not 軟件, 服务器→伺服器 not 伺服器)
• 3,490 curated terms: Human + AI reviewed, covering IT, medical, legal, finance, gaming, and more
• One-to-many character handling: Properly handles 发→發/髮, 面→面/麵, etc. based on context
• CLI tool: zhtw check . and zhtw fix . for batch processing
• CI/CD ready: GitHub Actions, GitLab CI, pre-commit hooks support
• Fast: Aho-Corasick algorithm, 100K lines < 1 second

Proposed Addition

Under "Public toolkits:", add:

• zhtw - Taiwan Traditional Chinese converter with 3,490 curated terms, focusing on Taiwan-specific terminology
