What changed

The Dirty status filter, and the number on its chip, now include a repo when any of its linked worktrees has uncommitted changes, even if the main checkout is clean.

• RepoView.dirtyAnywhere (Derive.kt): true when the checkout itself or any linked worktree has uncommitted changes.
• AppState.counts() and statusPredicate use it for "dirty".
• The Dirty chip's tooltip now mentions worktrees.
• New DirtyFilterTest covers: a clean checkout with a dirty worktree, a dirty checkout, everything clean, and a snoozed dirty worktree.

Why

Before this change, a repo was hidden from Dirty whenever its main checkout was clean, even if a worktree held uncommitted work.

For reviewers

• isDirty hasn't changed. It still drives the row's "modified" badges and the Commit button, and both only act on the main checkout. So a repo that's only dirty in a worktree appears under Dirty but has no Commit button.
• Snoozes are ignored here, as with isDirty: a snoozed worktree with changes still counts.
• Under Dirty, worktree sub-rows don't open on their own the way they do under the Worktrees filter. A row can match without showing why unless its worktree's unlanded-work badge rolls up.
• Not checked in the running app. Unit tests and detekt pass.
