chore: 0.82.0 — switcher-rebuild changelog, anchor caption, capture harness

The anchor caption 'Projekt / Bereich' truncated uselessly at the
rail width — 'Kontext'/'Context' fits and the tooltip carries the
full explanation. workspace_shots_test renders the anchor, the
open menu (checkmark, aggregated why-line), and the switching /
in-area identity bar per theme as the visual-proof harness.

 ## Unreleased
 
+### Changed (0.82.0)
+
+Workspace-switcher rebuild (persona review 2026-08-27; both
+high-rated findings fixed):
+
+- **Sealed-switch privacy race closed.** A connection switch now
+  runs inside an explicit switching window: the identity bar
+  announces the target BEFORE the client re-points, page pollers
+  pause, replies from the previous hub are dropped, and the sealed
+  context is announced only after the new hub answered healthy.
+  Guard: `workspace_switch_race_test`.
+- **Project filter survives the sealed round trip.** Entering an
+  area parks the shared-hub filter; returning restores it — live
+  state and prefs agree again.
+- **One global switcher anchor.** The switcher lives once in the
+  sidebar (context visible on every page, Cmd+P opens it); the four
+  per-page embeddings are gone. The sidebar endpoint label updates
+  with the workspace instead of lagging until the next health tick.
+- **Stopped areas ask before starting** ("Bereich starten?") —
+  running areas keep switching with one click.
+- **Honest scope tooltip** (the switcher applies everywhere, not
+  "this view"), **why-line at the aggregated sealed row** with a
+  jump to Settings → Security, **checkmark on the active entry**,
+  and the Cmd+K palette knows projects/areas (recent-use ranked,
+  sealed names honour the privacy setting).
+- **Sealed-aware flow list.** Inside a sealed area the editor lists
+  the instance's own flows dir (it used to keep showing the shared
+  hub's files), the editor state is dropped on a connection switch,
+  sample flows follow the hub's FlowSummary.sample flag (chip +
+  collapsed "Beispiele" group, editor 0.26.0), and an empty sealed
+  list offers "Beispiel-Flows importieren".
+- **Runs empty state names the filter** ("Keine Läufe in Projekt X"
+  + show-all action) instead of claiming the feature is off.
+
