v0.2.0 — Critical keyboard-lockout fix, window drill-down, multi-display panels

• Preview strip appearing at the far-left screen edge, or not at all
• Hover highlighting and tile clicking silently breaking after the list relayed out
• Wrong app activating when ⌘-Tab was pressed with the pointer resting over the panel
• Long filter queries widening the panel and shifting clicks onto the neighbouring app
• Preview strip covering the tiles it was meant to sit clear of
• Scrolling directly over the switcher panel doing nothing
• Shortcut recording assigning to the wrong action, or nothing at all
• Action shortcuts silently unreachable when the trigger itself uses ⌥ or ⌃ — Settings now
  refuses the conflicting combination and explains why
• Undefined behaviour in preview blank-detection that could drop real windows at random
• Screen captures continuing after the hover moved on

Internal

• Test target added: 43 tests over the trigger-modifier logic, shortcut conflicts, filtering
  and metrics
• Event-tap callback no longer performs SwiftUI layout, Accessibility calls, or
  LaunchServices lookups; tap-disable events are now counted and logged
• PanelGroup, PreviewCoordinator and TriggerModifiers extracted; SettingsWindow
  split into four files
• Settings panes rebuilt as two columns with tooltips, in a wider window
