Problem

Per-module diagram files (e.g. aiss_worker.mmd) show zero relationships even when the module imports from sibling modules. Cross-module relationships are captured correctly in overview.mmd but dropped when rendering isolated per-module files.

Example: aiss_worker imports WidgetType and WidgetStatus from commons, and WidgetJobData --> WidgetType appears in overview — but aiss_worker.mmd shows no edges at all.

What to build

In per-module rendered files, emit module-level dependency arrows to any sibling module that this module's types depend on. Show them as module-to-module edges (e.g. aiss_worker --> commons) rather than individual type edges, to keep the diagram readable.

Acceptance criteria

Per-module files show outgoing module-level arrows for each sibling module depended on
Arrow label shows the count of cross-module type relationships (e.g. aiss_worker --"3 deps"--> commons)
Intra-module type relationships still shown in full detail
Works for both Mermaid and ASCII renderers
Tests verify cross-module edges appear in per-module output
