The regenerate job replaced the media item without carrying its meta, silently dropping the user's alt text (and slide metadata) from the persisted post.
Copy meta from the freshly-locked post row (not the pre-render snapshot) inside the transaction, so an alt edit made while the multi-second render runs is kept rather than overwritten.
- Replaced the `regenerate_image` boolean with a `change_mode` string parameter in the PostImageRegenerator schema, allowing for more granular control over regeneration options.
- Updated methods in RegeneratePostMediaImage to handle the new `change_mode` values: `image_only`, `text_only`, and `both`.
- Enhanced documentation and comments to clarify the new regeneration logic.
- Added tests to verify correct behavior for different regeneration modes, ensuring that text and image changes are handled appropriately.
Let users adjust AI-generated slides in place via async job and Echo, while applying workspace brand, background, and text colors to image prompts. Autofill swaps site text/background colors for the image palette, and regeneration is blocked on finalized posts with safer job cleanup.
