Ln 301 Task Creator

This is a standalone worker that takes an approved task plan and actually creates the tasks in your tracker. It generates full task documents with seven required sections (Context, Implementation Plan, Technical Approach, AC, Affected Components, Code Impact, DoD), validates them, then writes to your kanban. Runs in two modes: CREATE expands the entire plan, ADD handles deltas when the coordinator already picked what's new. It pulls from coordinator context like traceability tables and discovery data to write decent Technical Approach sections, not just templated fluff. The pre-creation hook will block you if any of those seven sections are missing, which is aggressive but probably saves you from incomplete tasks hitting your board.
