chore: remove Docker test files - use local testing instead

Docker Desktop removed from system. Evolution testing uses local bun runtime.

Local testing approach:
- Uses bun runtime (already installed)
- Millisecond precision timing
- Fitness calculation with 2 decimal places
- Works without Docker/WSL2

Usage:
  powershell: docker/evolution-test/run-local-test.bat feature
  bash: ./docker/evolution-test/run-local-test.sh feature

Tests verified:
  - 54/54 tests pass (100%)
  - Time: 214.16ms precision
  - Fitness: 1.00 (PASS)
