chore: Remove non-blocking behavior from linting and type checking in CI workflow

This commit updates the CI workflow to remove the `|| true` command from the linting and type checking steps, ensuring that these checks will fail the build process if issues are encountered. This change enforces stricter quality control in the CI pipeline, requiring developers to address linting and type checking errors before proceeding with the build.
