Subject: [PATCH] Auto-join groups: /g and /gjoin auto-create if group doesn't
 exist
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Server: /join endpoint creates the group if it doesn't exist
- CLI TUI: /g <name> auto-joins before switching
- Web: /g <name> auto-joins before switching
- No more "group not found" errors — just /g ops and go
