DISCLOSURE: LLM-GENERATED TEXT

Why: Catalogs of 128 types or fewer never showed a row's exact type identity, so duplicate short names and custom display names stayed ambiguous.

What:

• Share one identity hint between both catalog renderers
• Hint the exact type name on hover in small catalogs
• Disable the elision tooltip so the explicit hint shows
• Cover colliding short names and custom display names

Refs #312

Type of Change

## Critical Rules

### C# and Unity

27. Name classes, structs, enums, records, and delegates in PascalCase; interfaces use PascalCase with an `I` prefix. Do not carry all-caps native typedef spellings into managed
    type names. Use a descriptive prefix such as `Native` when the idiomatic name would collide with a Unity or framework type. `.editorconfig` enforces these declarations as
    warnings.

Walkthrough

Catalog type labels now show namespace-qualified type names on hover. When a type has a distinct display name, the hint includes both the display name and full type name. Static and virtualized views use the shared hint logic.

Changes: Catalog type identity hints

Layer / File(s)	Summary
Type identity hints across catalog views Editor/DataVisualizer/NamespaceController.cs, Editor/DataVisualizer/UI/VirtualizedTypeCatalogView.cs, Tests/Editor/CatalogTypeIdentityHintTests.cs, Tests/Editor/CatalogTypeIdentityHintTests.cs.meta, docs/organizing.md, CHANGELOG.md	GetTypeIdentityHint returns the full type name, with a distinct display name as a prefix when applicable. Static and virtualized type labels use this hint. Namespace labels use the namespace key as their tooltip. Tests cover colliding short names and custom display names. The documentation and changelog describe the hover hint.

Follow-up Comments

Assert both namespace-label paths explicitly.

42-101: Trivial · Functional Correctness · Quick win

Assert both namespace-label paths explicitly.

The current fixture includes a virtualized namespace header, but the test does not require that header branch to execute. The static helper also skips namespace labels. A removed virtualized header or an incorrect static namespace tooltip could therefore pass these tests.

Update BuildStaticHints to verify each managed namespace has a rendered
namespace label with elision tooltips disabled and its tooltip set to the
namespace key. In BuildVirtualizedHints, track whether the namespace-header
branch is reached and assert that a header was rendered after binding all rows.

### Commit & Pull Requests

- Agent-written PR and issue bodies start with `DISCLOSURE: LLM-GENERATED TEXT`. CHANGELOG entries: one or two sentences, 300 rendered characters max (issue links do not count),
  verb-first, user effect first, no mechanism or narration; keep adjacent entries in tight lists without blank lines; never modify released entry text. CHANGELOG.md stays
  user-facing only (tests, CI, tooling, and release mechanics belong elsewhere).

### C# and Unity

29. Use `//` for standalone single-line comments and tool control directives only. Write ordinary multi-line explanations as one indented `/* ... */` block. Keep `///` XML
    documentation line-oriented. The C# source lint enforces this rule.

DISCLOSURE: LLM-GENERATED TEXT

The follow-up is applied in 1aa73ca. The static helper now asserts every managed namespace label disables the elision tooltip and keeps its key hint, and the virtualized helper tracks that the namespace-header branch binds before returning.
