# Description of Changes
- **What was changed:**
- Renamed top-level directories: `stirling-pdf` → `app/core`, `common` →
`app/common`, `proprietary` → `app/proprietary`.
- Updated all path references in `.gitattributes`, GitHub workflows
(`.github/workflows/*`), scripts (`.github/scripts/*`), `.gitignore`,
Dockerfiles, license files, and template settings to reflect the new
structure.
- Added a new CI job `check-generateOpenApiDocs` to generate and upload
OpenAPI documentation.
- Removed redundant `@Autowired` annotations from `TempFileShutdownHook`
and `UnlockPDFFormsController`.
- Minor formatting and comment adjustments in YAML templates and
resource files.
- **Why the change was made:**
- To introduce a clear `app/` directory hierarchy for core, common, and
proprietary modules, improving organization and maintainability.
- To ensure continuous integration and Docker builds continue to work
seamlessly with the reorganized structure.
- To automate OpenAPI documentation generation as part of the CI
pipeline.

# Description of Changes
- **What was changed**
- Updated `.github/labeler-config-srvaroa.yml` to match the new
`devGuide/.*` patterns instead of the old `HowToAddNewLanguage.md`
- Modified `.github/pull_request_template.md` to point to
`devGuide/DeveloperGuide.md` and `devGuide/HowToAddNewLanguage.md` for
the Developer Guide and translation-tags sections
- Updated the SSO link in `README.md` to point to the 'Single Sign-On
Configuration' section on docs.stirlingpdf.com instead of the outdated
Enterprise Edition page
- Changed the relative link in `devGuide/DeveloperGuide.md` to use
`../CONTRIBUTING.md` for consistency
- Added a new `devGuide/EXCEPTION_HANDLING_GUIDE.md` to document
standard exception-handling patterns and internationalisation best
practices
- Updated `devGuide/README.md` index to reflect the new location and
naming conventions for development guides
- **Why the change was made**
- To centralise all development documentation under a single `devGuide`
directory for better organisation and discoverability.
- To ensure that GitHub labeler rules and PR templates correctly
reference the new file structure.
- To introduce a clear, project-wide guide on exception handling,
improving consistency across Java, JavaScript, HTML/CSS, and Python
components.

# Description of Changes
This pull request introduces several improvements to enhance error
handling, internationalization, and documentation in the codebase. The
key changes include the addition of `ExceptionUtils` and `I18nUtils`
utility classes for consistent exception handling and internationalized
messages, updates to documentation paths, and modifications to existing
methods to integrate the new utilities.
### Error Handling Enhancements:
* **Added `ExceptionUtils` utility class**: Provides standardized
methods for creating and handling exceptions with internationalized
error messages, including specific handling for PDF corruption,
encryption issues, and other file-related errors.
* **Integrated `ExceptionUtils` into `CustomPDFDocumentFactory`**:
Updated `loadFromFile` and `loadFromBytes` methods to log and handle
exceptions using `ExceptionUtils`, ensuring consistent error handling
across PDF operations.

* **Updated `FileToPdf` to use `ExceptionUtils`**: Replaced direct
exception throwing with `ExceptionUtils.createHtmlFileRequiredException`
for unsupported file formats.
### Internationalization Improvements:
* **Added `I18nUtils` utility class**: Centralized access to Spring's
`MessageSource` for retrieving localized messages, enabling consistent
internationalization across the application.
### Documentation Updates:
* **Updated documentation paths in `CONTRIBUTING.md` and `README.md`**:
Changed paths to reference the new `devGuide` folder for developer
documentation and translation guides.
