[FEATURE] VSCode extension: make notification body clickable to navigate to the Claude tab (not just the View button)

Problem Statement

In the VSCode extension, when a notification fires (Claude finished a task or needs attention), clicking the body of the notification does nothing — the only way to navigate to the relevant Claude tab/panel is to click the "View" action button.

Notification bodies are conventionally expected to be clickable, so this is an unexpected friction point: the user's instinct is to click the toast itself, not hunt for the action button.

Proposed Solution

Make the notification toast body itself clickable, so that clicking anywhere on the notification (not just the "View" button) navigates to the Claude tab that emitted it.

Notes

• This is the inverse of #36094, where clicking the notification does switch tabs and the author wanted to avoid that switch. Here the issue is that clicking the body does not navigate at all — only the explicit action button works.
• Worth confirming whether this is a missing feature or a regression/bug: if the toast body is meant to navigate but doesn't, it may be a bug rather than a missing capability.

Environment

• VSCode extension
• macOS
