🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Decouple organization drags from projection payloads.
CloudTreeNode+Organization.swift makes remote workspaces organizable, while CloudTreeNode.isDragSource excludes workspaces. An empty workspace has no dragGroup because its placement group is empty. outlineView(_:pasteboardWriterForItem:) returns nil at the dragGroup guard before CloudTreeSurfaceDragPasteboardWriter can write .cloudSidebarRow. The existing drag test uses workspaces containing one terminal, so it does not cover this case. The drop path already uses the row ID as its organization identity.
Return a row-ID-only pasteboard item for organization-only rows:

Preserve PendingRemoteCreation until the remote close succeeds.
recordCreatedTerminal stores the creation receipt, and graph publication keeps the pending overlay until that receipt is reached. closeTerminal removes the overlay before runCloseCommand. If the close fails, a stale snapshot can replace or patch the catalog without the overlay and hide a terminal that still exists remotely.
Remove the pending creation only after the terminal-close command succeeds or the selector-not-found tab-close fallback succeeds.

Fixes #12360
Cloud folders and terminal placements now expose Pin/Unpin, Move Up/Down, and native same-parent drag ordering in the real right sidebar. Preferences persist on this Mac by machine and stable workspace/tab IDs; these actions do not rename, detach, duplicate, or restart terminals. The existing left sidebar keeps its ordering behavior.
Codex's native title hook previously wrote only the local process-title layer, while Cloud projections consumed the daemon graph; general auto-naming also rejected Cloud projections. Agent titles now use the same exact daemon-tab rename lane as user tab edits. Cmd+R resolves the owning workspace by its persisted binding or exact tab placement, so a terminal rename does not break workspace rename. The sidebar continues to consume accepted Cloud snapshots.
Title precedence: explicit user or remote placement labels beat automatic/process titles. Agent labels may update earlier agent labels. Matching daemon confirmations preserve local provenance; a newer deliberate remote rename/clear updates projections. Pending requests and daemon mutation receipts protect delayed snapshots, and request-generation ownership gates failure rollback. Agent writes additionally compare the expected placement name after obtaining the current graph. Workspace names remain independent from their terminal labels; differently named placements of one terminal remain independent. The flat terminal inventory shows a shared explicit label only when all placements agree, otherwise its process title.
Blue notification dots already existed. They now occupy a fixed leading slot immediately before terminal/folder icons; collapsed folders aggregate the same descendant unread state. Notifications raise only containing workspace folders within their machine and unpinned partition. They never automatically reorder terminals inside folders or in the flat Terminals section. Both sidebars use the same notification effect and live reorder setting; explicit manual moves remain separate.
Trade-offs: order/pins are Mac-local preferences, while daemon resource identity and names remain authoritative. A fixed attention slot consumes six points plus spacing to avoid icon shifts on unread/read transitions. Explicit remote labels are protected from automatic renaming; a user can clear a label to return to process/agent naming. No white-background change (#12449).
Validation on the pushed HEAD 52d6206:
edb1e4381179ea11f53a82b52c51ce054d590396, followed by the implementation commit. Hosted baseline and fixed runs (including compile-fixture and main-merge repairs) exercise the real socket hook and graph/outline behavior; failures before test execution are not counted as regression proof.
