Add mechanical pre-scan for typeset and layout (#345)

* Add mechanical pre-scan for typeset and layout commands.

Introduce --scope filtering, layout/type rule scopes, DESIGN.md font-size validation, and pre-scan steps in the skill references so agents run detect before LLM judgment.

Fixes #149

* Add isolated sub-agent orchestration for typeset and layout pre-scans.

Run the mechanical detector and visual assessment in parallel sub-agents so deterministic findings cannot anchor LLM judgment, matching the critique pattern Paul requested on PR #345.

* Fix: reject bare --scope so detect never scans unscoped by mistake.

When --scope had no value, the CLI dropped the flag and ran a full scan instead of failing, which could silently use the wrong rule set during typeset/layout pre-scans.

* Fix: require both typeset and layout assessments in sub-agents.

Close a loophole where agents ran only the mechanical pre-scan inline by interpreting "running both" as permitting one inline assessment.
