- Added Jest + ts-jest configuration (jest.config.js)
- Added global test setup with mocks (tests/setup.ts)
- Added trade factory helpers (tests/helpers/trade-factory.ts)
- Added 7 test suites covering Position Manager logic:
  - tp1-detection.test.ts (13 tests)

  - adx-runner-sl.test.ts (18 tests)
  - trailing-stop.test.ts (14 tests)
  - edge-cases.test.ts (18 tests)
  - price-verification.test.ts (13 tests)
  - decision-helpers.test.ts (28 tests)
- Added test documentation (tests/README.md)
