docs(m3): settle deterministic title and Call 2 design

Encode the recovered per-leaf title/short-description rule and the Call 2
input set into the point of record.

- REQUIREMENTS.md: METADATA-55 now produces the description only; METADATA-60
  carries the ruled input set; METADATA-80 is the deterministic title; new
  METADATA-81 is the deterministic spec-line short description; METADATA-85
  selects the patterns; REVIEW-15 declares the primary before Call 2;
  PUBLISH-55 carries an explicit name+SKU slug.
- CONTENT-WOO.md: per-leaf title and short-description catalog, slot order,
  dimension placement, and the Cook Woods provenance.
- PROMPTS.md: Call 2 inputs and output; the deterministic patterns are cited,
  not restated.
- CREATE.md, WOO-API.md, MILESTONES.md, task_breakdown.md updated to match.

Modeled on Cook Woods product-title form; the seven per-leaf prose templates
and Specialty cuts are parked in the M3 breakdown.
