Replace the in-place requeue of submit-uncertain unknown publish tasks
with an explicit supersede-and-create-new flow: manual retries mark the
old unknown task failed (manual_retry_superseded) and create a fresh task
carrying manual_retry / superseded_unknown_task_ids in its payload.
Also fold title-length validation into definitivePublishFailurePattern and
check the pattern before the publish_submit_uncertain guard so those
failures are released from the dedup set.

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.
