📝 Walkthrough

Walkthrough

Added TypeScript type checking to the lint workflow by introducing a lint:typecheck script that runs tsc --noEmit, updating the main lint script to execute this check, and configuring tsconfig to skip library declaration file validation.

Changes

Cohort / File(s)	Summary
Lint Configuration package.json	Added stop script and new lint:typecheck script using TypeScript compiler. Updated main lint script to include type checking alongside existing lint checks.
TypeScript Configuration tsconfig.json	Added skipLibCheck: true to compiler options to skip type-checking of declaration files in dependencies.

Poem

🐰 A typecheck hop through our code so bright,
Where errors now fail the lint, done right!
No more hiding imports gone astray,
TypeScript catches them every day! ✨

Check name	Status	Explanation	Resolution
Out of Scope Changes check	⚠️ Warning	The addition of a stop script is out-of-scope and unrelated to the linked issue #7 which focuses solely on type-checking failures in linting.	Remove the 'stop' script addition from package.json as it is unrelated to fixing the type-checking linting issue described in issue #7.
