refactor: DLO-16/17/18/20 — CLI simplification, config Pydantic, planner split, type system unification

DLO-16: Reduce cli.py from 1073 to 83 lines by registering Click commands from commands/*.py modules
DLO-17: Migrate Config to Pydantic BaseModel for validation
DLO-18: Split planner.py (826 lines) into orchestration, path rendering, and duplicate handling modules
DLO-20: Unify type system — convert 14 dataclasses to Pydantic BaseModel, keep TypedDicts as JSON schema hints
