Implement REQ-001~004 (dcy-001): scaffold the trex-core package (pyproject, trex_core/, tests/), port the slot pure domain into trex_core.domain.slot with import rewrites, add the EXPECTED_SLOT_FIELDS contract guard (test_contract), and port the state/service unit tests. Verification: 56 passed, ruff clean, import sweep shows zero external deps, public __all__ exposes no infra symbols, contract negative case reproduced. Align project-structure/runtime-flows baselines to the real tree. Sync SDLC tracking: REQ-001~004 → Implemented, BAT-001 → release-candidate.
