A queued message that changes model after an ExitWorktree restarts the
session, and promotion gives the provider thread a new session ID before
capture runs. The follow looked up that unopened session and skipped the
move, so the successor started in the removed worktree. The capture effect
now carries the session the finishing run used.

Branch adoption treated a checkout as exclusive when only threads in other
projects, or another project rooted there, used it. It now checks threads in
every project and project roots.
