Closes#1576
Adds `?serverUrl=<url>&transport=http|sse&autoConnect=<token>` URL-driven
auto-connect so a driver can reach a connected inspector with one navigate.
- `clients/web/src/utils/deepLink.ts`: `parseDeepLink()` (http(s)-only
serverUrl; `autoConnect` CSRF-gated on the per-launch API token),
`deepLinkParseStatus()`, `deepLinkConfigEquals()`, `DEEP_LINK_SERVER_ID`
(stable `deep-link` row so reloads reconnect to the same catalog row).
- App.tsx: ensure/connect effects (two-phase upsert-then-connect against the
hydrated list), `serversRef` read in `onToggleConnection`,
`connectErrorMessage` / `recordConnectError` recording connection-level
failures.
- InspectorView header: `data-testid="connection-status"` with `data-status`,
`data-error-message`, `data-deeplink` so drivers can `waitForSelector` and
read failure reasons without scraping toasts.
- Docs: deep-link scheme + `data-*` contract in clients/web/README.md.
Re-implemented informed by PR #1510 (33fac3f); adapted to the post-#1417
lifted-tab architecture and dropping the non-existent `normalizeServerUrl`
import in favor of `URL.href` canonicalization. Coverage gate green
(deepLink.ts 97.8/95.1/100/97.4).
Part of the #1579 decomposition (Wave 4).
