name: fix-types description: After each edit of typescript files, run this to catch type errors immediately.

Fix TypeScript Errors

1. Run npx tsc --noEmit to get all current errors
2. Group errors by file
3. Fix each file, re-running tsc after each fix
4. Do NOT consider done until npx tsc --noEmit returns 0 errors
5. If a fix causes new errors in other files, fix those too
