# 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
The `pre-commit` tool to sort the translations is really slow. It took
~40 seconds to run because it's using a parser which attempts to save
all of the formatting data from the Toml. Our translations toml is
pretty much entirely formatted anyway, so there's no point in trying to
preserve any of that data. The only thing we lose is 5 comments, none of
which are needed anyway and only appear in the US translation file. By
switching to Python stdlib `tomllib` reading and `tomli-w` for writing,
we can make the Toml formatting job take 2.11 seconds, where it used to
take 39.78s. The whole pre-commit job now takes 4.58 seconds.
# Description of Changes
The `pre-commit` commands in this repo are inconsistent with the rest of
the dev workflow, as they are impossible to run through Task and they
can cause CI to fail with no way for a developer to run the `pre-commit`
scripts after they've failed. This PR adds `task pre-commit` (and `task
pre-commit:fix`) and then hooks up the existing `pre-commit` hooks and
CI to call the Task rule, so if developers are using pre-commit hooks
then they should still work, but they're also runnable without using
pre-commit at all.
I think it'd be worth reviewing what we're actually running at
pre-commit in the future because I'm not entirely convinced by all of
the scripts that we are running, but this should at least make what we
have properly enforced and usable by all devs.
