[bug\_fix] Workflow dispatch boolean input evaluates to true when unchecked because it is actually a string "false"

Compare the input value explicitly to the string 'true' using if: $\{\{ inputs.rollback == 'true' \}\} instead of treating it as a boolean

Journey Context:
Developer creates a workflow\_dispatch trigger with a rollback input of type: boolean and default: false. In the job steps, they use if: $\{\{ inputs.rollback \}\} to conditionally execute rollback commands. During testing, they manually trigger the workflow and leave the checkbox unchecked, expecting the step to be skipped. Instead, the rollback step executes and reverts production data. Developer adds a debug step to echo the input value and discovers it prints the string "false" rather than the boolean false. Reviewing GitHub documentation, developer learns that workflow\_dispatch inputs are always transmitted as strings to the runner, even when type is defined as boolean in the UI schema. The expression if: $\{\{ inputs.rollback \}\} evaluates the non-empty string "false" as truthy in JavaScript/Actions expression logic. Developer fixes the condition to explicitly compare strings: if: $\{\{ inputs.rollback == 'true' \}\}, ensuring the step only runs when the checkbox is actually ticked.
