chore: v2.8.23 — workspace groups, inner repos in Changes (opt-in), sub-agent tokens counted

Workspace groups: named, foldable, ordered sidebar sections kept per
account (agenthub.workspace.groups); a workspace joins one from its menu,
a drop on the header, a drag under a row, or Alt+Up/Down past a group's
edge; headers drag to reorder; a folded header shows its most urgent
state; New workspace in this group; fold/unfold all.

Inner repos: GET /api/lanes/:id/repos + ?repo= on git/fs routes; the
Changes panel shows a parent folder's repos only when Settings -> Git ->
Changes panel turns it on (agenthub.changes.innerRepos, off by default).

Cost: the hook writer adds a session's sub-agent transcripts to its
tokens and hours (server/lib/subagent-usage.js) — a sub-agent on the
session's own model was never counted live (~8% of a week here); an
imported session is re-raised on every pass, so a claude -p run first
seen with an empty transcript no longer stays at $0 (~10%). A one-time
raise-only catch-up (user_version 5) re-reads ~/.claude/projects.

Also: omp install script may redirect to its exact install.redirect URL
(#85, repo-links test exempts it), native paste in the terminal.
