Metadata

Branch: task/ci-nox-parallel-sessions
Commit Message: feat(ci): run nox sessions in parallel to reduce CI wall-clock time
Milestone: v3.8.0
Parent Epic: #1678

User Story

As a developer, I want the CI pipeline to run nox sessions in parallel so that I can get faster feedback on my changes.

Acceptance Criteria

The CI pipeline runs the default nox sessions in parallel.
The overall CI run time is reduced.

Context

The default nox sessions are currently run sequentially. However, many of these sessions are independent of each other and can be run in parallel. For example, lint, format, and typecheck can all run at the same time.

Running these sessions in parallel will reduce the overall CI run time and provide faster feedback to developers. This can be achieved by using the --parallel flag when running nox, or by splitting independent sessions into separate CI jobs that execute concurrently.

Subtasks

Audit the default nox sessions to identify which are independent and safe to run in parallel
Update .forgejo/workflows/ci.yml (or equivalent) to run independent nox sessions concurrently
Validate that parallel execution does not introduce race conditions or shared-state conflicts
Update features/ci_workflow_validation.feature to assert parallel session execution is configured
Verify all nox stages pass after changes
Confirm coverage ≥ 97% via nox -s coverage_report
Run nox (all default sessions), fix any errors

Definition of Done

This issue is complete when:

All subtasks above are completed and checked off.
A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly, followed by a blank line, then additional lines providing relevant details about the implementation.
The commit is pushed to the remote on the branch matching the Branch in Metadata exactly.
The commit is submitted as a pull request to master, reviewed, and merged before this issue is marked done.
All nox stages pass
Coverage >= 97%
