• Improve vertical workspace transitions and Overview labels/corner-radius configuration.
• Expand runtime, daemon, configuration, and platform test coverage.

Testing

• Not run in this change request.
• Recommended: swift build
• Recommended: swift test

Greptile Summary

This PR replaces fixed per-monitor workspace copies with globally unique dynamic workspace stacks and adds persistence, monitor affinity, cross-monitor navigation, and vertical transitions.

• Adds named, ordinary, and trailing workspace lifecycle and positional targeting.
• Persists workspace topology within the current macOS login session and reconciles display disconnection and reconnection.
• Adds commands for workspace navigation, movement, reordering, and monitor targeting.
• Updates status output, configuration defaults, Overview presentation, SketchyBar integration, documentation, and tests.

Confidence Score: 5/5

The PR appears safe to merge based on the reviewed changes, with no concrete blocking or independently actionable non-blocking defect established.

The dynamic workspace lifecycle preserves active empty ordinary workspaces, maintains one trailing workspace, guards stale native-focus reactivation, and distinguishes explicit affinity changes from automatic display migration; transition safety checks also fall back to immediate layout when animation cannot proceed coherently.

Important Files Changed

Filename	Overview
Sources/DefiRuntime/RuntimeState.swift	Introduces persisted dynamic workspace topology, monitor affinity restoration, and the ordinary/named/trailing lifecycle.
Sources/DefiRuntime/CommandReducer.swift	Implements positional and named workspace navigation, cross-monitor moves, workspace reordering, and follow/send semantics.
Sources/DefiDaemon/WorkspaceTopologyStore.swift	Adds session-scoped atomic serialization and restoration of workspace topology.
Sources/DefiDaemon/DaemonDesktopSynchronization.swift	Reconciles persisted topology and dynamic workspace state with live displays, windows, and accepted native focus.
Sources/DefiDaemon/DaemonAnimation.swift	Adds all-or-nothing safety gating and immediate fallback for vertical workspace transitions.
Sources/DefiMacOS/AXFrameCoordinatorAnimation.swift	Reworks asynchronous animation scheduling, generation invalidation, lane writes, finalization, and timeout handling.
Sources/DefiConfig/Config.swift	Updates workspace defaults and parsing for optional named workspaces, monitor affinity, commands, and Overview corner radius.
Sources/DefiIPC/IPC.swift	Expands workspace status serialization to represent dynamic identity, position, ownership, kind, and application state.
contrib/sketchybar/plugins/defi_workspace_reconcile.sh	Reconciles SketchyBar items against the new dynamic per-display workspace state.
