[anujeet98]

• Add step to CI workflow to check linting.
• Replaced implicit and explicit any types with appropriate interfaces in ChatController.ts.
• Replaced non-deterministic waitForLoadState("networkidle") calls in Playwright tests with specific locator-based waits.
• Fixed empty catch blocks in test scripts to adhere to linting rules and improve error visibility.
• Refactored multiple jest.config.cts and jest.config.js files to jest.config.ts to aligns the project with modern ESM standards and leverages TypeScript for test configurations.
• Migrated the main application's next.config.js to next.config.ts
• Updated package.json in various libraries to fix peer dependency warnings and resolve linting errors.
