Implements video transformation features:
- Horizontal flip (mirror effect) using hflip filter
- Vertical flip (upside down) using vflip filter
- Rotation support: 90°, 180°, 270° clockwise using transpose filters
UI additions in Advanced mode:
- New "VIDEO TRANSFORMATIONS" section
- Two checkboxes for flip controls with descriptive labels
- Dropdown selector for rotation angles
- Hint text explaining transformation purpose
Filter implementation:
- Applied after aspect ratio conversion, before frame rate conversion
- Works in both queue-based and direct conversion paths
- Uses FFmpeg standard filters: hflip, vflip, transpose
Addresses user request to add flip/rotation capabilities inspired by Jake's script using -vf hflip.

Check if MSYS2 is already present by looking for the bash executable,
even if winget reports it's already installed. This allows the script
to continue with GCC installation instead of failing.

Replaced all emoji characters with standard ASCII status prefixes
to prevent encoding issues on Windows systems:
- ✓/❌ → [OK]/[ERROR]
- ⚠️ → [WARN]
- 📦/🔨/🧹/⬇️/📥 → [INFO]
This ensures the script works correctly on all Windows configurations
regardless of console encoding settings.

Batch files interpret unescaped parentheses as block delimiters,
causing "was unexpected at this time" errors and improper branch
execution. All parentheses in echo statements are now escaped with ^.

Capture ERRORLEVEL values immediately after each command execution
to prevent delayed expansion issues in nested conditionals. This
fixes the "was unexpected at this time" error and ensures proper
branch execution.
