code-modernization: harden topology viewer and template injection
Fixes from an adversarial review of the new viewer:

- pin d3 to 7.9.0 and load it via dynamic import with an explicit
  error panel when the CDN is unreachable (previously a blocked CDN
  produced a silent dark page — a real concern for restricted networks)
- coerce ids/names/loc at intake: a single missing name or non-numeric
  loc previously threw inside the render loop or propagated NaN through
  the pack layout, blanking the canvas with no error
- normalize flows/steps/edges defensively (null entries, missing steps,
  numeric ids vs string lookups)
- mirror the level-of-detail reveal rule in the hit test so clicks
  can't select nodes that aren't drawn
- scope the Escape shortcut so clearing the search box doesn't reset
  the viewport; set zoom clickDistance(4) so trackpad jitter doesn't
  swallow selection clicks
- round canvas backing-store size (fractional devicePixelRatio caused
  a reallocation every frame on 125%/150% display scaling)
- modernize-map: use braced ${CLAUDE_PLUGIN_ROOT} so substitution
  actually happens, assert the injection marker exists in the template,
  and correct the documented failure mode
