Rabbitty Beta 0.1.0-beta.44

Per-lane browsers — each project/worktree keeps its own page and login, restored across launches. New terminal-control MCP: agents can start, watch and kill dev servers in managed tabs owned by their pane (auto-reaped when the pane closes). AI Trail Product Note rewritten around an auto-generated summary. Browser pane drag-resize, mobile/tablet/desktop snap widths, and a hand-typed claude now picks up Rabbitty's MCP tools automatically.
