superstack 1.0.0

The idea-shaping interior is rebuilt around a visible, durable decision
sheet, and the platform claim is now proven on every push.

• Shaping: a triviality valve (regret, decision count, whether the
  output has a face); a read-back that states the idea's unsaid
  implications for free correction; topics cast under seven coverage
  lenses with a cold rival cast merged before question one and its
  outcome announced either way; a six-line expert decision brief before
  every nontrivial question (the decision, why now, what an expert
  notices, a starred recommendation with its reason, the real
  alternative, what closes the topic); regret-ordered walking where a
  high-regret topic stays open while its unknowns remain; batched
  question rounds (up to four independent questions per round); hedges
  and streaks of bare accepts mark a topic assumed rather than settled,
  and the two highest-regret assumed topics earn embodied re-rounds.
• The face law: anything with a face settles only by reacting to an
  embodied artifact, at a fidelity tier the user picks with its cost
  stated (an ASCII sketch, a skeletal page, or a full render in the
  native medium); receipts name the tier; picks below full fidelity are
  re-confirmed at the first real render; skipping embodiment requires
  the user's own words. The look gate now enforces the receipt: building
  on a face while a face topic sits unreacted bounces at claim time.
  Guarded red-first by hooks/test-face-receipt.sh.
• Sheet durability: the sheet is written at cast time, pointer line
  first, and touched at four defined moments only; one line per topic
  id, with the status doctor reporting every sheet and flagging
  duplicate ids.
• cocreate: owns rendered look probes (its visual refusal is gone);
  invoked under a sheet it settles one topic and returns; standalone it
  still covers an already-named artifact.
• Platforms: CI runs every suite on macOS, Linux, and Windows (under
  Git Bash) per push, with line endings pinned and a jq guard so
  fail-open hooks cannot fake a green. Two real portability defects
  fixed on the way: the root resolver now returns one path form on
  Windows, and the router-budget count is locale-pinned to characters.
