Problem

master-stack only supported a single master pane, so issue #50 could not expose a shared @mosaic-nmaster option or define multi-master promote and resize-master behavior.

Solution

Add @mosaic-nmaster as a window→global option with a default of 1, teach master-stack to expand the master region with tmux-native join-pane plus subtree rebalancing, update promote and drag-resize syncing for multi-master behavior, and cover the new semantics in integration tests and the README. Closes #50.
