react-doctor: rename generic handler names — `handleClick`/`handleChange` → action verbs (51 warnings)

[bntvllnt]

Source

`npx react-doctor . --json` — 51 warnings, single rule `no-generic-handler-names`.

Why this matters

Generic names (`handleClick`, `onChange`, `handleSubmit`) hide intent. `handleSelectComponent` / `handleAddTag` / `handleClearFilter` self-document and improve grep / refactor.

Sample

• `registry/default/timeline-scrubber/timeline-scrubber.tsx:277`
• `registry/default/knowledge-check/knowledge-check.tsx:502`
• `registry/default/relationship-inspector/relationship-inspector.tsx:113`
• `registry/default/comment-pin/comment-pin.tsx:176`
• `registry/default/jarvis-dock/jarvis-dock.tsx:89`
• `registry/default/ai-artifact/ai-artifact.tsx:485,526,562,600`

Acceptance criteria

• Rename all generic handlers to action-oriented names: `handle{Verb}{Object}`.
• Pattern: `handleClick` → `handlePinClick` / `handleAddSlide` / `handleSelectArtifact`.
• DOM event prop names (`onClick={handleX}`) stay generic — only handler definitions change.
• `pnpm doctor` reports 0 generic-handler warnings.

Run

```bash
pnpm doctor --explain registry/default/ai-artifact/ai-artifact.tsx:485
```
