- Use the `providedIn: 'root'` option for singleton services
- Prefer the `@Service` decorator over `@Injectable({providedIn: 'root'})` for new singleton services (Angular v22+)
- Use the `inject()` function instead of constructor injection

## Serving Locally

- **Demo app (SSR):** `pnpm build --configuration development && node dist/angular-devtools/server/server.mjs` → http://localhost:4000
- **Devtools SPA (hot reload):** `pnpm devtools:dev` → http://localhost:5173 (requires the SSR server running for RPC data)
- **Demo app (SPA, no SSR):** `pnpm start` → http://localhost:4200 (runs `ng serve` with SSR and hot reload; devtools popup + RPC work without a separate server)
- The devtools popup appears on the demo app page; click it to open the inspector panel
- Changes to `app/src/` (devtools SPA) are only visible via `pnpm devtools:dev`; the SSR server serves the npm-published assets
- To publish updated SPA assets: update versions in `packages/ng-devtools/package.json` and `packages/ng-devtools-assets/package.json`, then run `pnpm devtools:publish` (builds and publishes both `ng-devtools` and `ng-devtools-assets` to npm)

Match component rows by a unique declaration identity.

A scan can return two entries with the same selector. The current refresh uses the first selector match, so it can replace the selected component with the other entry and show that entry’s file-level providers. The row tracker and isSelected() also use only the selector, so duplicate-selector rows cannot be toggled independently.

Expose a unique identity from the scanner, such as file + scope.start, and use it for row tracking, refresh reconciliation, and internal selection. Keep the selector payload for select-component unless that separate highlighting contract also changes.

In `@app/src/pages/component-tree.ts` around lines 306 - 313, Add a stable unique
identity to scanner component records, such as the source file and declaration
start, and carry it into the component-tree `ComponentInfo`. Use that identity
for row tracking, refresh reconciliation, and `isSelected()` so
duplicate-selector components remain distinct; keep the selector payload for
`select-component` unchanged.
