[PostHog] Allow "No Match" branch to exit workflow

### Feature request ## Feature Request: Allow "No Match" Branch to Exit Workflow ### Summary Enable a simple way to configure the "No Match" branch of a condition to exit the workflow directly, without requiring additional condition or steps. --- ### Problem Currently, if a condition does not match, the workflow continues unless additional logic is added: - Users must add extra conditions or workaround steps to stop execution - This adds unnecessary complexity and visual noise - The intent ("stop here if no match") is not directly expressible --- ### Proposed Solution Introduce a direct option on the **"No Match" branch**: - Allow users to select **"Exit Workflow"** on the "No Match" path - Make it accessible directly from the branch UI (e.g. click on "No Match" → set behavior) - Ensure the workflow terminates immediately without executing further steps --- ### Benefits - Simpler and more intuitive workflow design - Reduces need for workaround conditions or extra nodes - Speed
