Ln 1000 Pipeline Orchestrator

This is the top-level orchestrator that drives a story from backlog to done by calling ln-300 for task planning, ln-310 for validation, ln-400 for execution, and ln-500 for quality gates in sequence. It parses your kanban board (file or Linear), lets you pick a story, asks all business questions up front in one batch, then steps through the four-stage pipeline while writing checkpoints and handling retries. The recovery system picks up where you left off if Claude drops mid-run. You'd use this when you want full automation on a single story instead of manually invoking each coordinator. It's built around the idea that coordinators emit artifacts and ln-1000 just reads them to know when to advance, which keeps the orchestration layer thin.
