fix: simplify CI to avoid Nx Cloud distributed execution failures

- Remove distributed execution setup that was causing agent failures
- Simplify to sequential execution of typecheck, lint, test, build
- Remove agent configuration to avoid 'agents were stopped due to error'
- Maintain parallel execution within each step for performance
