# Description of Changes
This PR modernizes the project's Python tooling across GitHub Actions by
migrating CI workflows from pip-based dependency management to `uv` and
aligning Python execution with the engine project's managed environment.
### What was changed
- Replaced `actions/setup-python` and ad-hoc `pip install` steps with
`astral-sh/setup-uv` across CI workflows.
- Configured shared `uv` dependency caching using
`engine/pyproject.toml` and `engine/uv.lock`.
- Updated Python script execution to use `uv run --project engine
--locked` for a consistent runtime environment.
- Replaced package installation steps with `uv sync` for the required
dependency groups (e.g. `tools` and `cucumber`).
- Added Docker image build validation for both production and
development AI engine images.
- Updated workflow cache configuration and Docker build context where
required.
- Removed obsolete Python requirements files that are no longer needed
after the migration.
- Applied minor Python code modernizations, including import cleanup,
modern built-in generic type annotations (`list[...]`, `tuple[...]`,
`float | None`), and small style improvements.
- Removed unnecessary Python formatter/linter extensions from the
development container configuration.
### Why the change was made
- Standardize Python dependency management across the repository.
- Reduce duplicated dependency installation logic in CI.
- Improve workflow performance through shared dependency caching.
- Ensure all Python utilities execute against the same locked dependency
set managed by the engine project.
- Simplify long-term maintenance by eliminating legacy requirements
files and pip-specific workflow steps.

# Description of Changes
This pull request introduces several improvements to pre-commit
configuration and automation, enhances error handling in scripts, and
updates dependencies and exclusions for code quality tools. The main
changes are grouped below:
**Pre-commit and CI workflow improvements:**
* The pre-commit workflow in `.github/workflows/pre_commit.yml` now runs
specific hooks (`ruff`, `ruff-format`, `codespell`, `gitleaks`,
`end-of-file-fixer`, `trailing-whitespace`) individually instead of
running all hooks at once, providing more granular feedback.
* The sync files workflow in `.github/workflows/sync_files_v2.yml` now
installs pre-commit dependencies and runs the `toml-sort-fix` hook to
ensure TOML files are consistently sorted.
* Added the `toml-sort-fix` hook from the `toml-sort` repository to
`.pre-commit-config.yaml` for sorting TOML files in the locales
directory.
**Pre-commit configuration and dependency updates:**
* Updated the `ruff-pre-commit` repository version from `v0.14.8` to
`v0.14.14` in `.pre-commit-config.yaml`.
* Updated the `codespell` hook to expand the ignore words list and to
exclude the `frontend/public/vendor` directory.
**Script improvements and error handling:**
* Replaced bare `except:` clauses with `except Exception:` in
`scripts/convert_cff_to_ttf.py` for safer error handling.

* Minor code cleanup in translation validation scripts by removing
unused variables.

* Removed unused `progress` variable assignment in
`scripts/counter_translation_v3.py` for clarity.

## Summary
- add a `PdfJsonConversionService` that serializes PDF text, fonts, and
metadata to JSON and rebuilds a PDF from the same structure
- expose REST endpoints for `/pdf/json` and `/json/pdf` conversions
using the existing convert API infrastructure
- define JSON model classes capturing document metadata, font
information, and positioned text elements
## Testing
- `./gradlew spotlessApply` *(fails: plugin
org.springframework.boot:3.5.4 unavailable in build environment)*
- `./gradlew build` *(fails: plugin org.springframework.boot:3.5.4
unavailable in build environment)*
