[idea] Move a complete tab between spaces

[tmcinerney]

idea / problem

Spaces are useful for grouping work, but that grouping changes over time. A tab can start as general tooling or an investigation, then become part of a specific project or incident.

Today, a tab is fixed to the space where it was created. Moving panes individually means reconstructing the layout in the destination space, which is awkward and can disrupt a running task.

requested change

Allow a complete tab to move from one space to another while keeping its existing pane layout and running terminals intact.

A UI action such as dragging a tab onto a space, or a “Move tab to space…” context-menu action, would cover the main workflow.

why you want this

This would let me reorganize Herdr around the work that is active now, rather than the structure that existed when I created each tab. I could promote a tab into an incident or project space without restarting processes or reconstructing a multi-pane layout.

I searched for similar discussions. #771 covers reordering tabs within a space and explicitly leaves cross-space tab moves out of scope.
