CRITICAL FIX: Resolve Qt video player display issues and implement clean interface 

- FIXED: Qt video black screen issue - WindowStaysOnTopHint interference eliminated
- FIXED: Database configuration persistence preventing always_on_top fix from taking effect
- FIXED: Threading architecture - Qt player now runs properly on main thread
- FIXED: Window behavior - main window goes behind other apps, overlay stays on top
- ADDED: Clean minimal interface - removed all toolbars, menus, status bars, context menus
- ADDED: Complete keyboard control - all functionality via shortcuts (F11, S, Space, M, Escape)
- UPDATED: Documentation with critical fixes and resolution details
- UPDATED: CHANGELOG.md with version 1.2.1 improvements
- UPDATED: README.md with latest critical fixes and interface changes

This resolves the core video display problem and achieves complete functional
parity between main.py and test_video_debug.py with professional interface.

## [1.2.1] - 2025-08-20
### Fixed
- **Critical**: Qt video player display issue completely resolved - video frames now render properly on Linux
- **Critical**: WindowStaysOnTopHint interference with Qt video rendering eliminated by fixing always_on_top configuration
- **Critical**: Database configuration persistence issue resolved - old cached settings no longer override new defaults
- **UI**: Removed all toolbars, menu bars, status bars, and context menus for clean minimal video player interface
- Main thread architecture properly implemented for Qt event loop with background components on separate threads
- Window focus and OpenGL context management fixed for proper video frame rendering
- Configuration loading sequence corrected to prevent database overrides of updated settings
### Changed
- Qt player interface now completely clean with no UI chrome (toolbars, menus, status bars removed)
- All functionality accessible via keyboard shortcuts (F11: fullscreen, S: stats, Space: play/pause, M: mute, Escape: exit)
- Database reset mechanism implemented to clear old cached configuration on major setting changes
- Main application window behavior now matches test script (can go behind other applications)
- Overlay window properly separated from main window for correct layering
### Technical Details
- Fixed settings.py default always_on_top: bool = False to prevent WindowStaysOnTopHint on main window
- Implemented database configuration reset to eliminate cached settings conflicts
- Removed setMenuBar(), setStatusBar(), and setContextMenuPolicy() calls for clean interface
- Enhanced PlayerWindow.setup_ui() to disable all UI chrome elements
- Maintained complete keyboard control functionality while removing visual clutter

## Recent Critical Fixes (Version 1.2.1)
### ✅ Video Display Resolution
**RESOLVED**: The critical video black screen issue that prevented video frames from rendering on Linux systems. The root cause was identified as WindowStaysOnTopHint interference with Qt video widget rendering.
**Technical Fix**:
- Changed `always_on_top: bool = False` in settings.py
- Implemented database configuration reset to eliminate cached overrides
- Fixed window flag application logic in PlayerWindow.setup_ui()
### ✅ Threading Architecture Optimization
**RESOLVED**: Qt player now properly runs on main thread with background components correctly separated.
**Technical Implementation**:
- Qt event loop runs on main thread for proper OpenGL context
- Message processing moved to QTimer-based main thread execution
- Background threads properly daemonized for clean shutdown
### ✅ Clean Minimal Interface
**IMPLEMENTED**: Completely removed all UI chrome for professional video player appearance.
**Interface Changes**:
- Removed: Menu bars, toolbars, status bars, context menus
- Maintained: Full keyboard control functionality
- Added: `setMenuBar(None)`, `setStatusBar(None)`, `setContextMenuPolicy(Qt.ContextMenuPolicy.NoContextMenu)`
### ✅ Window Management
**FIXED**: Proper window layering and behavior matching test script functionality.
**Behavior**:
- Main video window: Goes behind other applications (normal window behavior)
- Overlay window: Stays on top as intended for overlay content
- Both windows properly synchronized and positioned
