Add interactive Cleanup Map visualization

[Lagom-TA]

Summary

• Add an optional desktop Cleanup Map companion for Survey and Change workflows.
• Include a cleanup-specific schema, validator, renderer, examples, and portable standalone HTML delivery.
• Vendor the trimmed Archify Architecture renderer and desktop viewer core, preserving licenses and adaptation notes.
• Document the visual-report truth boundary, handoff format, and validation evidence.

Behavior and boundaries

Written proof records remain authoritative. The map visualizes confirmed authored topology; it does not prove runtime impact or deletion safety. Unresolved topology or findings that gain no explanatory value from a map fall back to text reports with exact source locations.

Survey uses Locate / Trace / Cut / Decide; Change uses Before / Cut / After / Verify. The renderer requires Node.js 18 or newer, has no npm runtime dependency, and emits standalone HTML without external font requests.

The viewer preserves keyboard navigation and reduced-motion behavior. First-paint layout is stabilized to prevent stage-rail detection from shifting the page after load.

Validation

• 13 renderer tests passed on Node.js 18.20.8 and 26.7.0 during pre-submission validation; all 13 passed again before this submission.
• Both Survey and Change fixtures passed contract and standalone artifact checks.
• Browser review covered 1280x800 and 1440x900, light and dark themes, first load, stage changes, evidence disclosure, focus, zoom, and rapid switching.
• Page scroll position, document height, and panel/workspace coordinates remained stable in those checks.
• Git whitespace/diff checks passed.

Scope and submission note

Only the Architecture renderer and desktop interaction surface needed by Cleanup Map are bundled. Other diagram types, publishing, gallery flows, and general Archify repository tooling are excluded.

This resubmits the change from #1, which was not publicly visible to maintainers. Existing commit authorship is preserved.
