Help text no longer chooses a text editor

6 source lines; 8 focused declaration tests pass (0.06 s).

Annotation documentation was flowing through the same foreign metadata reader as editor capabilities. Annotated[str, "help", PreparedChoices(...)] declared str before the prepared catalog, so Toad's shared field registry chose StrEditor instead of the existing model picker or finite-choice dropdown. Numeric and boolean values could be misclassified in the same way.

The shared metadata boundary now treats a help string as documentation with no value-kind declarations. The actual annotated value still contributes its own complete MRO, and declared metadata still supplies capabilities first. No per-widget workaround, duplicate selector, generated catalog family, or import guard.

Evidence

• Traced NewThreadCliCommand -> CatalogTargetField.editor_hints -> PreparedChoices.declares -> FormBridge declarations -> DeclaredViews.showing.
• Observed Model and Thinking resolving to StrEditor before this fix, despite their catalog declarations being intact.
• tests/test_declared_views.py: 8 collected, 8 passed, exit 0; checks help text with str/int/bool and prepared editor metadata.
• NRA insert/patch operations authored both source and checks.

P189's Toad UI opening/submission repair remains on Toad #1751; this fixes the shared declaration owner rather than special-casing its consumer.
