Replace single-shot acquireHotView with retainHotView/releaseHotView
plus a minute-level reaper that closes views idle beyond 5 minutes and
never evicts a view while it still has live retainers. Wrap adapter
calls in try/finally so a failing publish/query still releases the
view. Sample process metrics every minute and expose hot-view policy
and process snapshot via the runtime snapshot for diagnostics.

Plan 0 (workspaces): add workspaces + workspace_memberships schema, extend
JWT/Actor/claims with primary_workspace_id, seed default workspace per tenant,
thread workspace_id through tenant monitoring quota.
Plan A (desktop skeleton): new Electron app (apps/desktop-client) with main/
preload/renderer, shared Vue component package (packages/ui-shared), and server
surface — desktop client registration + token rotation + heartbeat, SSE task
event stream, desktop accounts/tasks/content handlers, publish job endpoint,
and supporting repositories, services, sqlc queries, and migrations.
Hard cutover per plan: remove browser-extension monitoring callback endpoints,
stub legacy media API in admin-web, and delete monitoring_callback_handler.go.
