feat(tui): add Kimi WebBridge install entry to /plugins panel (#1494)

* feat(tui): add Kimi WebBridge install entry to /plugins panel

Surface a hardcoded Kimi WebBridge entry at the top of the Official tab in the /plugins panel. Selecting it opens the WebBridge install page in the user's browser instead of going through the plugin install flow, since WebBridge is a browser extension plus local daemon rather than an installable plugin package.

* fix(tui): restrict WebBridge open-url shortcut to the pinned row

Match the hardcoded pinned WebBridge entry by object reference instead of by id. A curated or custom marketplace entry on the Third-party tab can legitimately reuse the kimi-webbridge id; routing by id hijacked Enter on those rows and opened the WebBridge page instead of installing. The Official tab still dedupes a same-id official catalog entry so the pinned row is not duplicated.

* fix(tui): label WebBridge plugins row as "open in browser"

The previous "webpage" status did not make it clear that selecting this row opens an external page rather than installing in-app. "open in browser" states the action directly and contrasts with the install label on regular plugin rows.

* test(tui): navigate past pinned WebBridge row in marketplace install tests

Two message-flow tests pressed Enter on the Official tab assuming index 0 was the Kimi Datasource entry. The hardcoded Kimi WebBridge row now leads that tab, so move down one row before installing.
