Key design decision: All 20+ language profiles (regex patterns, stub detectors, extension routing) are now pure JSON data. The single index.ts file is a thin runtime that loads and compiles those patterns at startup. To add a new language, you just append an entry to language_profiles.json -- no recompilation, no new parser class.

To use: cd mcp-drift-state-tracker && npm install && npx tsx src/index.ts
