feat(rpgmaker): add image translation work log

- Record regions, coordinates, original text, and translations in one Markdown log
- Preserve relevant entries across reruns while preventing duplicates
- Add regression coverage for the new logging instructions

+
+Create or update exactly one UTF-8 Markdown log at:
+
+`{{EDITABLE_IMAGES_FOLDER}}/image_translation_log.md`
+
+Keep the log lightweight and reviewable. Do not create per-image logs or embed images, binary
+data, or long command output. Include a short run summary with the backup location and validation
+status, followed by one table row per text region with these columns:
+
+| Image | Region / role | Coordinates `(x, y, width, height)` | Original text | Translated text | Disposition | Notes |
+| --- | --- | --- | --- | --- | --- | --- |
+
+Use image paths relative to the editable image folder and source-image pixel coordinates. Use a
+disposition such as `translated`, `preserved`, `skipped`, or `review`. Keep notes brief, recording
+only useful context such as a dynamic-value keepout, glossary gap, reconstruction method, or
+validation concern. Add one image-level row with `none` coordinates for a reviewed image that has
+no player-visible text, so the log accounts for every PNG in scope.
+
+If the log already exists, update or replace stale rows for images processed in the current run
+instead of duplicating them. Preserve still-relevant rows for images outside the current run.
+Escape Markdown table separators and represent intentional line breaks with `<br>` so the table
+remains readable.
