feat(deps): add pytest-xdist for parallel test execution

[ayeshakhalid192007-dev]

What does this PR do?

Adds pytest-xdist support to enable parallel test execution across multiple worker processes, as requested in #1.

Root Cause

Tests were running sequentially in CI, causing slow feedback loops. There was no parallelisation mechanism in place despite pytest-playwright having built-in support for pytest-xdist workers.

Changes

• pyproject.toml: Added pytest-xdist==3.8.0 to project dependencies
• .github/workflows/devRun.yml: Added -n 2 flag to the pytest CI command
• pyproject.toml: Added asyncio_mode = "auto" under [tool.pytest.ini_options] to ensure async compatibility with xdist workers

Expected Impact

• Tests run across 2 parallel workers in CI, reducing total test execution time
• Each worker gets its own Playwright browser instance via pytest-playwright's built-in xdist support — no changes to fixtures or test files required
• No breaking changes to existing test behaviour

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation update

Checklist

• My code follows the style guidelines of this project
• I have performed a self-review of my own code
• My changes generate no new warnings
• All existing tests pass with parallel execution (pytest -n 2)
• I have verified the CI workflow runs correctly with the -n 2 flag

Closes #1

📝 Walkthrough

Walkthrough

This pull request enables parallel test execution by adding the pytest-xdist==3.8.0 dependency and configuring the CI workflow to run tests with the -n 2 flag, allowing tests to execute concurrently on two workers during the devRun test suite execution.

Changes

Cohort / File(s)	Summary
CI Workflow Configuration .github/workflows/devRun.yml	Added -n 2 flag to pytest invocation to enable parallel test execution with xdist.
Project Dependencies pyproject.toml	Added pytest-xdist==3.8.0 to [project].dependencies to support parallel test execution.

44-44: Make xdist worker count configurable instead of hardcoding 2.

Line 44 works, but parameterizing workers makes CI tuning easier without editing workflow code.

Proposed refactor

count "-n 2" with a configurable workflow variable: define a job- or
