Session 63, Step 3: Workflow improvements: step sync, story locking, side tabs, userStoryId in JSON:
- Remove resolved issue from Workflow Select Issues list immediately
- Re-add issue to Workflow Select Issues list when un-resolved
- Move wfInstrPreviewToggle, Cancel and Save buttons next to Paste button in toolbar
- Auto-save story and set UserStoryProcessedDate when Next step is clicked
- Lock story to Preview mode with hourglass avatar on Next step click
- Persist story locked state across page reload via UserStoryProcessedDate
- Guard against accidental tab close with unsaved stories warning and localStorage save
- Dirty indicator (green title) for unsaved user stories in Instructions list
- Add Cancel button to Step 3 Generate that reverts Instructions step
- Prepend instructions blockquote to generated text when 'Include instructions' is checked
- Step 4 Process Output: side tabs for concurrent running session steps
- Side tab title: Session X step Y + session name subtitle + current step icon
- Include step.userStoryId in generated input JSON for managed sessions
- Update aisman-instructions-template.md with step.userStoryId in input and output JSON
- Update output file validation: userStoryId vs inputText rules for managed vs direct sessions
