fix(overview): decouple navigation from Hyprland dispatch

[enhulsman]

Problem

I noticed some odd behavior in the overview while using it on my dual-monitor setup. Pressing Tab to browse workspaces would close the overview entirely, because it dispatches workspace r+1 to Hyprland and the IPC event triggers HyprlandFocusGrab.onCleared. Moving my mouse over windows would jump the cursor around since focuswindow is dispatched on hover. With an empty search field, pressing Enter did nothing when I expected it to close the overview and go to whatever workspace I was looking at. And clicking a window would occasionally close the overview before the transition finished because the focus dispatch happens immediately.

These all turned out to be the same underlying problem: the overview dispatches Hyprland commands while the focus grab is active, and the resulting IPC events feed back and close it.

Solution

Decouple the overview from Hyprland dispatch by introducing local workspace tracking:

• `trackedWorkspaceId`: local property that tracks which workspace the user is navigating to, without telling Hyprland
• Workspace switches only dispatch after the overview closes and the focus grab is deactivated
• Navigation intent bubbles up through `OverviewWindow → Overview → ScrollingOverview → OverviewPopup` without side effects
• After navigating to a same-monitor window, the cursor is restored to the click position
• Removed `focuswindow` dispatch on hover so the cursor no longer warps
• Added `"workspace"` to the HyprlandData IPC ignore list to prevent spurious UI updates during navigation
• Enter with an empty search now closes the overview, which just felt like the obvious expected behavior

Worth noting: when the search field has text but zero matching windows, `navigateToSelectedWindow()` still returns early (no match to navigate to). I left this as-is since Enter with a non-matching query being a no-op feels less surprising than closing the overview and losing the user's typed query.

Files Changed

• `modules/bar/workspaces/HyprlandData.qml`: add "workspace" to IPC ignore list
• `modules/widgets/overview/OverviewPopup.qml`: trackedWorkspaceId tracking, close-then-dispatch onAccepted
• `modules/widgets/overview/OverviewView.qml`: pass trackedWorkspaceId down
• `modules/widgets/overview/Overview.qml`: local workspace tracking, signal chain, cursor restoration
• `modules/widgets/overview/OverviewWindow.qml`: signal-based navigation, remove hover dispatch
• `modules/widgets/overview/ScrollingOverview.qml`: trackedWorkspaceId passthrough
• `modules/widgets/overview/ScrollingWorkspace.qml`: signal-based navigation

Testing

1. Open overview, press Tab: workspace indicator moves locally, overview stays open
2. Open overview, press Enter (no text): overview closes, switches to tracked workspace
3. Open overview, hover over windows: no cursor warping, no focus change
4. Open overview, click window: overview closes, then focuses window
5. Open overview, double-click window: navigates to window, cursor position preserved
6. All above on multi-monitor
