Improve Zed agent thread history to update across all open windows (#47803)

Previously, each Agent panel created its own `ThreadStore` instance, so
thread history updates wouldn't sync between open windows. Users had to
close and reopen windows to see threads created in other windows.

Now `ThreadStore` is initialized once as a global and shared across all
windows. When any window saves a thread, ThreadStore::reload() calls
cx.notify(), which notifies all NativeAgentSessionList observers,
causing all windows' history views to refresh.

Note: This only works for the native Zed agent. It also is only
improving the history view (thread titles)—this PR does not sync edits
between multiple windows when the same thread is open in each.

Release Notes:

- Improved Zed agent thread history to update across all open windows
```
