fix(sessions): show all sessions across all projects (closes #48) (#50)

* fix(sessions): load all sessions across projects, not just active directory

Closes #48

Root cause: loadSessions() used connState.client which carries the
active connection's directory as x-opencode-directory header. The server
filters sessions by that directory, so only the current project's sessions
were visible.

Fix: call clientForDirectory(undefined) to get a no-header client.
The server then returns sessions from all projects.

The session row UI already showed a directory badge (shortDir from
session.directory), so no UI change is needed — each session already
displays its project folder name.

* fix(sessions): preserve directory when opening rows

Carry each listed session directory into the route so selection, messages, and follow-up operations use the matching project client.
