Part C of #1057. Scene content/actions/widget generation, retry, action parsing, interactive post-processing, buildCompleteScene with injectable sceneId, and PBL single-call planning re-seated on AICallFn (pure core + kernel + package-relative planner assets; loop planner stays app-side behind the injected pblLoopFallback with provider/abort classification). Purely additive — app source untouched until Part D. Package 0.2.0.
Part B of #1057. Outline primitives, buildOutlinePrompt (single-source prompt construction with golden snapshots), logger injection, JSON repair, and the bare-Node second-consumer smoke script with CI coverage. Shim-first: no app-side behavior changes; duplicated prompt assets guarded by a CI parity check until Part D.
