Create a new GitHub Actions workflow file .github/workflows/code-quality.yaml with:

• Trigger on PRs to main and release-* branches
• Path filters: workspaces//e2e-tests/
• Dynamic discovery of e2e-tests directories
• ESLint, Prettier, and TypeScript validation
• Quality gate job for aggregated status
• Only validate changed files - don't block PRs for pre-existing issues in unchanged files

Key Behavior:

• Workflow only runs when e2e-tests files are changed
• Validation runs only on workspaces that have changes
• Pre-existing issues in unchanged files do NOT block the PR

Acceptance Criteria:

• Workflow triggers only on e2e-tests file changes
• Discovers e2e-tests directories with changes dynamically
• Runs lint:check, prettier:check, tsc --noEmit only on affected workspaces
• Does NOT fail for issues in unchanged files
• Provides clear pass/fail status on PR
