# Summary
- Adds desktop file tracking: local paths are preserved and save buttons
now work as expcted (doing Save/Save As as appropriate)
- Adds logic to track whether files are 'dirty' (they've been modified
by some tool, and not saved to disk yet).
- Improves file state UX (dirty vs saved) and close warnings
- Web behaviour should be unaffected by these changes
## Indicators
Files now have indicators in desktop mode to tell you their state.

# Limitations
- It's a bit weird that we still have files stored in indexeddb in the
app, which are still loadable. We might want to change this behaviour in
the future
- Viewer's Save doesn't persist to disk. I've left that out here because
it'd need a lot of testing to make sure the logic's right with making
sure you can leave the Viewer with applying the changes to the PDF
_without_ saving to disk
- There's no current way to do Save As on a file that has already been
persisted to disk - it's only ever Save. Similarly, there's no way to
duplicate a file.

# Description of Changes
This pull request completes the removal of Thymeleaf template engine
support and documentation from the Stirling-PDF codebase and developer
guides, reflecting the project's full migration to a React-based
frontend. It removes all references to Thymeleaf in code, configuration,
and documentation, and updates guides to focus exclusively on the React
SPA architecture. This streamlines the codebase and clarifies the
development workflow for contributors.
**Codebase cleanup: Thymeleaf removal**
- Removed all commented-out Thymeleaf dependencies and related
configuration beans from `build.gradle` and `AppConfig.java`
(`app/common/build.gradle`,
`app/common/src/main/java/stirling/software/common/configuration/AppConfig.java`)
[[1]](diffhunk://#diff-2a1a21726f33b05d16451237c68d6df91a5f4a58419d839715f3f1538a9a14aeL32)

- Fully commented out (as a precursor to future deletion) the
`FileFallbackTemplateResolver` and `InputStreamTemplateResource`
classes, which were only used for Thymeleaf template resolution
(`app/common/src/main/java/stirling/software/common/configuration/FileFallbackTemplateResolver.java`,
`app/common/src/main/java/stirling/software/common/model/InputStreamTemplateResource.java`)
[[1]](diffhunk://#diff-e2bc7614074316b972355cb7dda47b98f75b00eb6b2ca4f143a680ab2803dcd8L1-L49)

**Documentation updates: React-only focus**
- Removed all instructions and references to migrating or developing
with Thymeleaf templates in `DeveloperGuide.md` and `ADDING_TOOLS.md`,
including detailed Thymeleaf usage examples, migration steps, and
translation key usage in templates

- Updated architecture descriptions in `CLAUDE.md` to reflect that the
frontend is now exclusively a React SPA and that Thymeleaf templates
have been fully replaced
[[1]](diffhunk://#diff-6ebdb617a8104a7756d0cf36578ab01103dc9f07e4dc6feb751296b9c402faf7L131-R132)

**Labeler configuration update**
- Removed labeler rules for files related to the old Thymeleaf-based web
controllers and UI directories, as these are now obsolete
(`.github/labeler-config-srvaroa.yml`).
These changes ensure the codebase and documentation are consistent with
the new React-only frontend approach, reducing maintenance overhead and
potential confusion for contributors.

# Description of Changes
Remove custom response handler from Merge. Also make `filePrefix`
mandatory for `multiFile` tools to make the output more visually
different since you get a new 'V1' file rather than 'V2' of the current
file.
