Command center tabs, recent workspaces, and archived workspace search (#9689)

* feat(app): command center tabs, recent workspaces, and agents in workspace search

The command center gets All · Workspaces · Files · Actions tabs under the search
field. Tab and Shift+Tab rotate them on web, a tab keeps the query and starts at
its top, and Backspace on an empty field returns to All. ⌘P opens on Files in
place of the Files scope chip.

All leads with the three most recent workspaces other than the open one. Agent
rows are gone: an agent's title now finds its workspace, which shows the agent on
a third line and opens that agent's tab.

The selection now follows the first result until the user moves it, so rows that
load above it do not leave it on the row below.

* feat(app): archived workspaces in command center search

A query in All or Workspaces now also finds archived workspaces through
agent history, appended after the active matches. Archived rows show the
archive time and an Archived badge, and open the workspace's latest agent
where it can be unarchived. Hosts without history search contribute
nothing. History's archived badge moves into a shared ArchivedBadge.

* fix(app): put the command center divider between the field and the tabs

The tabs belong to the results, not the search field, so the rule now
separates the field from the tab bar. The tab-rotation test also pins the
list's top, since the tabs no longer live inside the header it measured.

* fix(app): rank agent matches by quality, keep background workspaces out of Recent, explain Files off-workspace

- Score each agent together with its workspace's title and subtitle, so a
  query split across them ("payments login") finds the row, and pick the
  workspace's own match only when it is as good as its best agent match.
  Across workspaces, match quality now ranks before own-versus-agent.
- Carry the workspace's background flag through the project summary and
  leave background workspaces out of Recent workspaces, as the sidebar
  does. A query still finds them.
- The Files tab outside a workspace says "Open a workspace to search
  files" instead of "No matches".

* fix(app): settle command center selection, name agents only for loose matches, drop Files off-workspace

- Name a workspace's agent only when the workspace's own text does not match
  contiguously and the agent does; a change-request hit is always an own match.
- Follow the first row only until every source for the query and tab has
  loaded, then keep the selection by ID so reorders do not move it.
- Projects stay loading until an online host's workspaces have arrived; the
  agent directory reports ready first.
- Outside a workspace there is no Files tab and All lists no files; the All
  placeholder names only what the available tabs search.
- The unqueried Workspaces list follows the sidebar's Show background setting.

* fix(app): keep Projects loading honest, rank own-name matches by their agents too, refresh archived search after archive

- The command center waits for online hosts' workspaces itself instead of
  through useProjects. useProjects held isLoading until workspaces
  hydrated, but a failed workspace request never hydrates, so the
  Projects screen could spin forever.
- A workspace that matches on its own name is ranked by the better of
  that match and its agents', so typing into an agent title shared with
  another workspace no longer drops it below that workspace and back.
- Archiving a workspace marks agent history stale. Archived search reused
  a cached page that still listed the agents as active, so a workspace
  archived in the last 30 seconds matched in neither list.

* fix(app): decide command center agent matches by match class

One rule now picks both what a workspace row shows and how it ranks. A
match falls in a class: every word at a word boundary, a word inside a
word, or scattered/misspelled. A row names its agent only when the agent
matches in a closer class than the workspace's own text, never on a
change-request hit. Rows rank by class, then own text ahead of an agent,
then score, then recency.

The previous rules chose the ranking candidate and the displayed
candidate separately, so each fix moved the edge case: positional tier
gaps named agents mid-word, and ranking by a hidden agent let a mid-word
name outrank a word-boundary one with nothing on screen to explain it.

* style(app): format command center workspace search import

* fix(app): settle archived search when no history host is reachable

With no searchable host online, the history query is disabled under a new
key, and keepPreviousData kept serving the old key's rows as placeholder
data. Archived search read that as still waiting for results, so the
command center selection never settled and followed every re-rank.
Previous results now stand in only while the query can run.
