Merge branch 'main' into ocrchange

# Description of Changes

Please provide a summary of the changes, including:

- **What was changed**  
- Removed individual `actions/create-github-app-token` steps and
replaced them with a centralized `setup-bot` custom action across all
workflows.
- Updated steps to use `steps.setup-bot.outputs` instead of
`steps.generate-token.outputs`.
- Standardized step names and ordering (e.g. checkout before bot setup).
- Simplified `sync_files.yml` by eliminating the `read_bot_entries` job
and directly using `setup-bot` outputs.
- Added or adjusted permissions where required (e.g.
`repository-projects: write` in `licenses-update.yml`).

- **Why the change was made**  
- To centralize and standardize GitHub App authentication logic, reduce
duplication, and improve maintainability of CI workflows.
- To ensure a consistent bot identity (app slug, token,
committer/author) across all actions and PR automation.
- To streamline workflow configurations and make future updates easier.

+# Codex Contribution Guidelines for Stirling-PDF
+
+This file provides high-level instructions for Codex when modifying any files within this repository. Follow these rules to ensure changes remain consistent with the existing project structure.
+
+## 1. Code Style and Formatting
+- Respect the `.editorconfig` settings located in the repository root. Java files use 4 spaces; HTML, JS, and Python generally use 2 spaces. Lines should end with `LF`.
+- Format Java code with `./gradlew spotlessApply` before committing.
+- Review `DeveloperGuide.md` for project structure and design details before making significant changes.
+
+## 2. Testing
+- Run `./gradlew build` before committing changes to ensure the project compiles.
+- If the build cannot complete due to environment restrictions, DO NOT COMMIT THE CHANGE
+
+## 3. Commits
+- Keep commits focused. Group related changes together and provide concise commit messages.
+- Ensure the working tree is clean (`git status`) before concluding your work.
+
+## 4. Pull Requests
+- Summarize what was changed and why. Include build results from `./gradlew build` in the PR description.
+- Note that the code was generated with the assistance of AI.
+
+## 5. Translations
+- Only modify `messages_en_GB.properties` when adding or updating translations.
+
