"Hide sleeping" swept each project's main workspace out of the sidebar as soon as
it had no live PTY, browser tab or agent — even with "Hide default branch" off.
For a project whose only row is that workspace (a folder workspace, a fresh
clone, a detached-HEAD main), the entire project vanished with no in-place way
back.
Adds a shared `isSleepingSweepExemptWorkspace` predicate keyed on
`isMainWorktree` rather than the branch name, so folder workspaces (no branch),
detached-HEAD mains, and SSH rows whose head/branch are blanked while a provider
is disconnected all stay put. Wired into `computeVisibleWorktreeIds` (sidebar,
Cmd+1-9, workspace board), the jump palette's duplicate inline pass, and mobile's
`filterWorktrees`.
Ships default-on with an escape hatch: a persisted
`alwaysShowDefaultBranchWorkspace` setting surfaced as "Except default branch"
under "Hide sleeping". Explicit "Hide default branch" still wins, since it
filters before the sleeping sweep.
Mobile reads the setting but never writes it back, so a desktop opt-out can't be
clobbered by a filter tap before the ui.get roundtrip lands.
Combines the two PRs open against #8873. #8966's exempt set is a strict subset of
this one, so its production diff was subsumed rather than ported; its jump-palette
render harness and e2e spec were carried over, and are the only such coverage here.
