docs(tac): tighten product artifact stage gates

Deepen the Codex product-work guidance with explicit artifact stages, production-readiness receipts, model-timing assumptions, and a deletion/simplification review criterion so cheap implementation does not create ungoverned prototype slop.

- model-timing assumptions are explicit: some artifacts are kept to retest when model capability changes;
- complexity budget is tracked because autonomous loops tend to add code; deletion/simplification is a first-class review criterion.
