Pull request overview
Adds an automated maintenance workflow to keep the repository’s Nix flake.lock up-to-date by running a weekly scheduled update and opening/updating a PR with the changes.
Changes:
- Introduces a scheduled GitHub Actions workflow that updates
flake.lockweekly. - Uses DeterminateSystems actions to install Nix (for portability) and create/update the PR for lockfile changes.

LGTM! Unfortunately we have to merge it to test from main. I'll do that.

Summary
nix flake updateevery Sunday at 06:00 UTC and opens a PR with the updatedflake.lockRequired setup
A
FLAKE_UPDATE_GITHUB_TOKENrepository secret should be configured with a PAT (or GitHub App token) that hascontents:writeandpull-requests:writescopes on this repository.This is needed because pushes made with the default
GITHUB_TOKENdo not trigger other workflows (GitHub's recursive prevention). Without this token, the workflow still works — a PR is created — but CI won't run on it automatically. In that case, close and reopen the PR to trigger CI manually.Test plan
