* Support background and focused terminal presentation modes
* Add `presentation` field ('background' | 'focused') to terminal
creation to control focus behavior.
* Prevent terminal creation from stealing UI focus by default.
* Return discoverability warnings when default terminal presentation
fails, unless explicit background mode is selected.
* Update orchestration SKILL.md to clarify review-only worker
completion rules and named owner handoffs.
* Prevent background terminal sessions from auto-activating
Ensure that terminal tabs created with 'background' presentation (such
as background agent sessions or locally backed renderer transports) do
not automatically activate or get selected as the active tab on remote
or mobile sessions.
- Add a selectIfNoActiveTab option to control auto-activation on mobile
- Set presentation to 'background' for remote runtime transports and
agent background sessions
- Skip tab auto-selection when the presentation is background
* Keep background terminal create payloads focused
