harden Draw.io parsing and validation across XML declarations, compressed pages, containers, and connector analysis
add deterministic YAML Diagram IR v1/v2 authoring with multi-page output and a formal v2 JSON Schema
add dependency-aware TypeScript layout and obstacle-aware orthogonal routing
add objective all-page quality diagnostics for clipping, text overflow risk, placeholders, external assets, palette spread, and density
preserve the existing TypeScript/NodeNext/pnpm/Taskfile/@maxgraph/core technology stack
Validation

Dependency audit
The independent exact-tree review reported 0 production vulnerabilities using temporary npm lock resolution. The repository-native pnpm audit command could not be run because pnpm is absent from the execution shell; no runtime stack change was introduced.
Stack constraint
No Python, Graphviz, ELK runtime, MCP service, browser service, or mandatory Draw.io Desktop dependency was introduced.
