Summary

Fixes the API data the MCP hands to agents: wrong xmlns, missing members, wrong inheritance, and internal classes listed as usable. Stacked on #13; merge #13 first.

Changes

• xmlns per type, not per DLL. The type extractor resolves each type's xmlns with System.Xaml's XamlSchemaContext over the DLLs' own XmlnsDefinition/XmlnsPrefix attributes, replacing the hand-typed ASSEMBLY_XMLNS table. Falls back to clr-namespace: where no Infragistics xmlns applies; nested classes get Outer+Inner. Official prefixes (igOutlookBar, igReporting).
• Theme classes show their styles. Generic base classes are now linked and static properties read, so DataPresenterRoyalDark.CellValuePresenter etc. appear (1 → 63 members).
• Keys and commands are listed with the properties, marked (static field): DataPresenterCommands 0 → 71, DockManagerBrushKeys 0 → 130.
• Inheritance keyed by assembly + full name. Same-named classes no longer overwrite each other (the chart Axis showed members of the Excel ChartObject).
• No more escaped type names. type-info.json strings are decoded (Action\u003CToolCommand\u003E → Action<ToolCommand>), with a build guard against regressions.
• Internal classes are no longer indexed. 6,907 → 5,343 pages, list_wpf_components 191 → 189; 89 names an internal class used to win now document the public class.

Results

	Before	After
Public types with a wrong xmlns	1,984	0
list_wpf_components entries with a wrong xmlns	18 (XamTabControl, XamPager…)	0
Pages with a wrong base / foreign inherited members	488 / 190	0 / 0
Pages with escaped type names	474	0
Internal-class pages	1,653	0

Verification

• xmlns: System.Xaml resolver on all 5,180 public types: every one resolves to the exact class.
• Real WPF build: 308 sampled XAML files using the generated xmlns compile. The same sample with the old xmlns fails 130 files.
• Reflection: inheritance checked on all 5,312 public pages, and the internal-class list cross-checked independently. No public page removed.
• Gates: all pass (C# and TS smoke tests, typecheck, pack, validate:package). New smoke checks fail on the old build and pass on the new one.

Notes

• validate:package minimum lowered from 6,000 to 5,000 API files (5,343 now).
• Doc counts updated: "5,300+ public types", "189 controls".
• CLAUDE.md / DEVELOPMENT.md describe the new extractor output (__xaml, __baseTypes, __nonPublicTypes).

🟡 Changes recommended

The escaped-type-name regression guard accepts malformed data instead of failing the build.

What changed in this PR

Corrects generated API data so the WPF MCP server provides more accurate namespaces and public member references.

Changes:

• Resolves namespaces per type and inheritance by assembly-qualified name.
• Includes static styles, keys, and commands while excluding internal types.
• Updates runtime formatting, smoke checks, validation thresholds, and documentation.
