* fix(runtime): recover stale session owners and await retirement
* fix(runtime): preserve session hydration and smoke compatibility
* test(runtime): cover empty and unindexed session owners
* feat(cli): make terminal close the canonical workspace teardown
* fix(preload): align ssh termination result type
* test(runtime): assert folder hydration owner
* fix(runtime): fence legacy terminal stop by worktree host
* fix(preload): reconcile ssh result import with main
* fix(runtime): keep same-id sibling hosts out of workspace close
The stale-owner fallback in the session controller re-routed any worktree whose
catalog partition had no tabs to whichever other partition held tabs. Only
`runtime:` environment ids rotate across relay restarts; `repoId::path` legitimately
repeats across hosts, so an SSH workspace close could retire the local copy's
tabs and resume records, or flip owners mid-close and strand the SSH PTY.
Restrict the fallback to runtime hosts, and pin the session partition once per
workspace close so record clearing targets the partition that owned the tabs.
* test(runtime): give the cross-host close fixture a real resume record
* fix(preload): take main's ssh-bridge import order so the merge stays duplicate-free
