feat(squeekboard-toggle): add availability detection, hover icons, and settings

[blackteaextract]

Summary

• Squeekboard availability detection — checks whether sm.puri.OSK0 is present on the D-Bus session at startup (via busctl) and monitors it live (via dbus-monitor); widget reflects unavailability with an error icon, color, and tooltip
• Hover icons — icon previews the action on hover (show/hide), adapting to bar position; can be disabled in settings
• Settings UI — new Settings.qml with two toggles (hide widget when unavailable, disable hover icon) and a manual recheck button
• Monitor resilience — dconf watch and dbus-monitor processes auto-restart on unexpected exit

Preview:

What changed vs 1.0.0

Main.qml

• Added pluginApi property (required for future IPC / settings access)
• Added gsettingsOk and squeekboardOk flags, combined into available
• Added squeekboardChecker (one-shot busctl call) for initial availability check
• Added squeekboardMonitor (dbus-monitor) for live NameOwnerChanged events on sm.puri.OSK0
• stateMonitor now auto-restarts on exit and re-runs stateChecker on restart
• Added recheckState() function for manual re-sync from settings

BarWidget.qml

• Reads available from mainInstance and gates click/color/icon on it
• Dynamic icon: error state → current state → hover preview (direction-aware for bottom bars)
• Tooltip keys extended: tooltip.noGsettings, tooltip.noSqueekboard
• hideWhenUnavailable and disableHoverIcon settings wired up

Settings.qml (new)

• NToggle for hide-when-unavailable
• NToggle for disable-hover-icon
• Recheck state button with 1.5 s confirmation feedback

i18n/

• Added tooltip.noGsettings, tooltip.noSqueekboard
• Added settings.hideWhenUnavailable.*, settings.disableHoverIcon.*, settings.recheck.*
• All 18 language files updated

manifest.json

• Version bumped 1.0.0 → 1.1.0
• Added settings entry point
• Added defaultSettings for hideWhenUnavailable and disableHoverIcon

How to test

• Load the plugin and confirm the widget shows the current keyboard state
• Click the widget — keyboard should toggle; icon and tooltip update
• With Squeekboard running: hover over widget — hover icon should appear (unless bar is vertical)
• Stop Squeekboard (pkill sqkeekboard) — widget should switch to error state without reloading the shell
• Start Squeekboard again — widget should recover automatically
• Open settings: toggle "Hide when unavailable", stop Squeekboard — widget should disappear
• Open settings: toggle "Disable hover icon" — hover icon should stop appearing
• Open settings: click "Recheck state" — button shows confirmation for 1.5 s
• Verify settings persist across shell restarts
