0.10.0 — mobile-first, and a loop a weak model cannot skip

Mobile-first, and a design loop that a weak model cannot skip. Everything here
was measured on live runs at the capability floor (Haiku), and most of it exists
because an instruction the agent could choose to ignore was ignored.

Added

• The loop: decide → spec → mockup → make → critique. decide
  runs once per project. The other four run per page, feature or functionality.
  mockup is new: a low-fidelity grayscale drawing, reviewed before any code,
  in HTML (the default), Figma or Google Stitch. Every region is labelled with
  its measured size, and the phone frame draws the menu open as well as closed.
• jig verdicts <surface>. A critique's reader arms write one verdict per
  rule to .jig/critique/<surface>/screen.json and code.json; this command
  decides whether the review is complete and computes the counts the attestation
  reports. It refuses invented ids, a rule filed by the wrong arm, a rule judged
  twice, an n/a whose reason says the rule was never read, and rendered: true
  with no artefact. A screen pass with no render is skipped, not ran.
• jig probe. One expression the critique evaluates in any browser at 360,
  768 and 1280. It operates the phone menu (does it open, does aria-expanded
  change, does the label read as close, does Escape close it), measures sideways
  scroll, and reads whether the styles and tokens actually applied. verdicts
  refuses a verdict the probe contradicts.
• jig gate, run by a Stop hook — off unless you ask for it with
  install --hook, or say yes when an interactive install offers it. It blocks
  an agent from finishing while the files it changed fail check, or while the
  /jig command it just ran left its work unfinished. After three attempts it
  lets go and says the work is not done. --yes never adds it: that is the
  agent's path, and nobody is there to consent. update moves an existing hook
  to the new version and never adds one.
• Six mobile rules. D-111 a page that never adapts, D-112 100vh,
  F-113 form text that zooms on iOS, D-114 a bar under the notch,
  D-115 a page that scrolls sideways, E-116 a menu that cannot be opened or
  cannot say it is open.
• H-117 a token name nothing declares. A var() naming a property no file
  declares makes its whole declaration invalid, so the page silently loses its
  font, spacing and borders. Three of four live builds shipped exactly that,
  and every file-based check passed them.
• P-14 site navigation, composed for the phone first: what to show at each
  width, a named menu control whose state is visible and announced, aria-current
  styled from the attribute, and no sideways-scrolling nav row.

Changed

• spec writes a whole composition per screen size, phone first, with
  regions: and nav: at each — not one composition and a note about narrow
  screens. A menu button at a width where the links fit is refused: where the
  button sits is the project's decision, whether it exists at that width is not.
• make finishes on three gates: a pasted JIG_CHECK with no mechanical
  errors, a region-by-region comparison with the approved mockup at each width,
  and each size's spec fields accounted for.
• critique operates the page instead of only looking at it, judges the
  P- patterns the spec uses, and sends its findings back to make until the
  page is clean or the user accepts what is left, by id.
• decide records what is still open in an Unresolved section, and writes
  only reasons the owner gave.
• explain searches every line of every rule, and the free sections of the
  reference, not only titles and preambles.
• check warns when jig.config.json is unreadable or declares a mode the
  token layer does not import, and counts those warnings in JIG_CHECK.
• L-01's squint test runs on a grayscale render where a browser exists;
  reading the source is the fallback, not the equal.
• init --yes says what it did not decide — no surface mapping, and
  re-running init after you declare one.
