Metadata

Branch: chore/ci-parallelize-nox-sessions
Commit Message: chore(ci): parallelize independent nox sessions for faster local and CI builds
Milestone: v3.8.0
Parent Epic: #1678

Background and Context

The noxfile.py currently runs several independent sessions sequentially (lint, format, typecheck). These sessions have no dependencies on each other and can be run in parallel to significantly speed up local development and CI builds. This is a quality-of-life improvement for all contributors and aligns with the project's goal of fast feedback loops during development.

Expected Behavior

The lint, format, and typecheck nox sessions should execute in parallel when invoked together, reducing total wall-clock time for local quality checks.

Acceptance Criteria

nox is configured to run lint, format, and typecheck sessions in parallel.
Parallel execution does not introduce race conditions or other issues.
The local development workflow is demonstrably faster when running all three sessions.
All existing nox sessions continue to pass.

Subtasks

Investigate nox parallel execution options (e.g., --no-venv, -p flag, or nox-poetry parallel support)
Update noxfile.py to configure lint, format, and typecheck sessions to run in parallel
Verify that parallel execution does not introduce race conditions or output interleaving issues
Update any relevant documentation or contributor guides referencing nox usage
Tests (BDD): Add/update scenarios in features/ to assert parallel session behavior if applicable
Verify 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 (chore(ci): parallelize independent nox sessions for faster local and CI builds), 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 (chore/ci-parallelize-nox-sessions).
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%.
